Is it Ever OK to Tell Your Boss Youre Looking for a New Job

Is it Ever OK to Tell Your Boss Youre Looking for a New Job It can be tricky when you’re job hunting and trying to keep it a secret from your boss and fellow employees. You might have to  resort to fake doctor appointments or a family emergency to get time off for interviews. In another roadblock, your current job can prevent you from listing coworkers or members of management as recommendations on your resume. Is there any professional way  to tell your boss you’re job hunting to make it easier for yourself?Examine Why You’re Job HuntingBefore checking out those job search sites, you may want to ask yourself why you are planning on finding a new job. Ask yourself if you are looking for a larger salary, more responsibilities, or are using the opportunity to switch career paths. One way to examine your  reasons  for job hunting is to  create a list of positive and negative points of your current job. After completing the list, you will have a good idea why you really want a change.Times When You Can Tell Your Bos sActually, there are times when you can tell your boss you are job hunting without many problems. For example, if your spouse has taken a job in a different city and you are forced to move, it’s fine to share your news. Perhaps you have bought a new house on the other side of town, and the commute would add too much time to your daily routine. Or maybe you  have health problems that could force you to take a job with less stress, or your spouse just retired and you want to work closer to home. Logistical reasons for a job change are fine to share with your boss.Think about the Repercussions FirstHaving a good relationship with your employer can make telling him or her  a possibility. In some instances, if you are an employee who knows you are valued, you might be offered a raise, another position in the company, or added responsibilities as an enticement to get you stay with the job. However, whether you tell your boss is strictly a judgment call. If you call it wrong, yo u could be out looking for a job earlier than you had planned and without the backup of your current position.Timing is EverythingYou’ve been on several interviews and the hiring manager is talking about when you start your new job. Is it time to inform your boss and put in your resignation? Until you have actually signed the contract for your new job, you should  hold off on telling your current employer. You aren’t actually hired until those papers are signed, and someone else might come along and snag the new job you thought you had. When your new contract is signed, then is the time to tell your employer. It is also a good idea to let your new employer know that you need to give notice to your current boss with enough time for a replacement to be hired to fill your position. Your new boss will appreciate your courtesy.Knowing when to tell your current employer that you are job hunting can be an important consideration to protect yourself. Job hunting with the abi lity to find all the listings that suit your position is also important, and there are easier ways than searching through job classifieds. TheJobNetwork can help. After you fill out your work interests and qualifications, TheJobNetwork searches 24-hours a day for listings that match your description and sends those listings to you as an email alert. All you do is sign up for job match alert to get started.

Free Essays on Addiction

Addiction is defined as â€Å"being abnormally dependent on something that is psychologically or physically habit-forming† (dictionary.com). There are many different types of addiction. Drug, alcohol, nicotine and caffeine addiction are just a few types. It is important to examine addiction and describe the problems it causes in all aspects of a person’s life. The signs of addiction are obvious. Addiction starts with drug abuse, when a person makes the choice to use drugs, but addiction is not just â€Å"a lot of drug use.† Recent scientific research shows that not only do â€Å"drugs interfere with normal brain functioning creating powerful feelings of pleasure, but they also have long-term effects on brain metabolism and activity.† (Henderson 15). At a certain point, changes occur in the brain that can turn drug abuse into addiction, a relapsing illness. Those addicted to drugs suffer from compulsive drug and usage and cannot stop by themselves. Treatment is necessary to end this addiction (nida.nih.gov/Infofax/understand.html). Another sign is the compulsive use of drugs or alcohol regardless of negative consequences. Addiction can be caused by numerous factors. People can be genetically predisposed, which means that a person’s genetic makeup could cause it. It also can be caused by psychological and social problems. Uncontrolled stress can be a major factor as well. It also just may be that the substance is highly addictive and alters the brain’s biochemical structure (Bender 45). The substances do this using the brain’s reward system, also known as the mesolimbic reward system. The mesolimbic reward system raises the body’s dopamine level, which gives off the feeling of pleasure (Bender 46). Addicitve substances hijack this reward system and flood the brain with dopamine. This causes the addict to crave the substance rather than being involved in normal daily activities because they don’t feel the same am...

Free Essays on Addiction When most people think of addiction, they think of potheads and alcoholics. Although those are the most common types of addiction, there are also more bizarre things like sex addicts and gambling. In a sense, every person has a form of addiction. Weather to caffeine, or food, or cleaning, they are all small kinds of addiction. Like, if you do not have your daily dose of triple shot espresso in the morning, you will go insane, or whenever you feel an extreme emotion, you feel the urge to eat. There are some people who have extreme additions, that destroy families, demolish their former selves, and lose everything they ever had, just for a drink or a few hits. Having an addiction can scar a family and leave charred relationships in its wake. Most people dealing with addiction have done it for most of their lives, and have no intention of stopping, or even realize that they have a problem. Denial is normal in such situations. Because they deny that anything is wrong, the other party in the relationship begins to question their own habits. Growing up with an alcoholic father, I spent most of my childhood questioning myself. I did not understand why he would forget to pick me up on Sundays, or why there was always a half-gallon of Black Velvet in the back seat of his truck. When he was drunk, he would call and tell me that my life goals were not good enough, and that I should consider other routes. He would comment on my weight (which was never really a problem) and criticize my every move. He lied about scratches and bruises and broken ankles from bar fights, blaming them on his job. My mother lived with these habits for seventeen years befo re she finally had enough. His addiction had taken over his mind and actions, until he was not the person he used to be. He was an uncaring, alcohol fixated human, who was willing to lose his wife and child over a bottle. Alcohol destroyed my family, and I know that I am not alone. If you think about... Free Essays on Addiction Addiction is defined as â€Å"being abnormally dependent on something that is psychologically or physically habit-forming† (dictionary.com). There are many different types of addiction. Drug, alcohol, nicotine and caffeine addiction are just a few types. It is important to examine addiction and describe the problems it causes in all aspects of a person’s life. The signs of addiction are obvious. Addiction starts with drug abuse, when a person makes the choice to use drugs, but addiction is not just â€Å"a lot of drug use.† Recent scientific research shows that not only do â€Å"drugs interfere with normal brain functioning creating powerful feelings of pleasure, but they also have long-term effects on brain metabolism and activity.† (Henderson 15). At a certain point, changes occur in the brain that can turn drug abuse into addiction, a relapsing illness. Those addicted to drugs suffer from compulsive drug and usage and cannot stop by themselves. Treatment is necessary to end this addiction (nida.nih.gov/Infofax/understand.html). Another sign is the compulsive use of drugs or alcohol regardless of negative consequences. Addiction can be caused by numerous factors. People can be genetically predisposed, which means that a person’s genetic makeup could cause it. It also can be caused by psychological and social problems. Uncontrolled stress can be a major factor as well. It also just may be that the substance is highly addictive and alters the brain’s biochemical structure (Bender 45). The substances do this using the brain’s reward system, also known as the mesolimbic reward system. The mesolimbic reward system raises the body’s dopamine level, which gives off the feeling of pleasure (Bender 46). Addicitve substances hijack this reward system and flood the brain with dopamine. This causes the addict to crave the substance rather than being involved in normal daily activities because they don’t feel the same am... Free Essays on Addiction Alcoholism in Young Adults Alcoholism in Young Adults Alcoholism and alcohol abuse is a growing problem in our society. Daily, people are injured and killed in alcohol-related accidents and this has an effect on each and every person as a result of these occurrences. Whether we are personally involved or have directly suffered from the activities of someone who is under the influence of alcohol, we all suffer from the negative consequences of alcohol. Since we have those who choose to abuse these privileges we need to develop consequences for them. By learning what leads people to drink alcohol, and how this affects their lives, we can then determine what actions need to be taken to help remove ourselves from our ever-increasing attraction to alcohol. Because the abuse of alcohol often begins with adolescents and young adults, most research is based around them. At this particular time in life we hope to find out why these young adults choose to drink, and what motivates them to drink. Michael and Rebecca C. W indle, in their research, were able to show several reasons that provided incentives for adolescents to consume alcohol. Using a written survey, it was determined that the high-school students being studied used alcohol to cope with problems in their lives, including "task-oriented", "emotion-oriented", and "avoidance coping (Windle & Windle, 1996, p. 551)." The only major discrepancies in results between the sexes became obvious when it was shown by Windle and Windle that girls were more likely to use alcohol for avoidance and emotion-oriented coping than were boys, but the boys were more likely to have alcohol problems (Windle & Windle, 1996). Also found was that adolescents drank less often for social reasons than for the aforementioned coping reasons (Windle & Windle, 1996). However, coping motives were responsible for an increased consumption of alcohol (Windle & Windle, 1996). A surprising result of this study was that th... Free Essays on Addiction Addiction Addiction†¦Ã¢â‚¬ ¦drugs, alcohol, life; from the eyes of some one who observes it and experiences it every day. Almost everyone in the world is affected by the wrath of addiction whether it be by themselves, family members, peers, idol’s or enemies. The definition of addiction is, â€Å"the quality or state of being addicted.† Which I think is quite an understatement†¦. In the following I will talk about the stages of addiction, people I know and how they react to addiction, personal experiences as well as different treatment plans and how people react to them. The addiction process and stages of addiction can vary greatly from person to person. Depending on personality type, lifestyle and background they can go from a once a week pot smoker to a crackhead in 6 months or a once a week pot smoker to some one who does every drug out there on a somewhat regular basis but can stop at any time and is still completely functional. People with addictive personalities are much more likely to abuse drugs and go through the process quickly and more harshly than people with self-control that can do many different things without acting obsessive and compulsive. The term instant gratification applies directly to the different personality types. Those of whom who crave instant gratification are much more likely to have jobs like waiting tables, stripping or Manpower Temporary services where they get paid the same day they work. Rather than working all week to get paid just once. A person’s background can also make a big difference in their likelihood of becoming an addict, but it can also have a reverse effect. The majority of people would think that if you are exposed to your parents drinking and doing drugs than you would be more likely to partake in these activities as well. More often than not this is true, but like everything in life there is always exceptions. Some adolescents feel the need, or have the urge to rebel agai...

Assess how national culture impacts on the international business Essay

Assess how national culture impacts on the international business environment, giving examples - Essay Example Trans-national companies like Sony, General Motors, carry a distinct identity of the culture they first operated in despite now having worldwide operations. Quite simply speaking the culture is studied as synonym of culture. We often come across terms like the Japanese culture, the British culture, the Australian culture, or Russian culture. The countries, like Canada, US, UK, and India with many different racial, religious, or regional cultures are called multi-cultural countries. Yet many countries located in a specific geographical area can be bound by the thread of a common culture. For example, the Caribbean countries like Jamaica, Trinidad and Tobago, and Antigua can be referred to as having a common culture. It is very important to describe the word ‘culture’ as it is construed in the context of business management. Some of the definitions offer interesting insights into the importance; the ‘national culture’ has for business leaders, professionals, management gurus and academics. Culture is variously defined (cited by Fougere, 2007) as ‘that complex whole, which includes knowledge, belief, art, morals, law, custom, and other capabilities acquired by man as a member of society (Tylor); the collective programming of the mind, which distinguishes the members of one human group of another (Hofstede); a system of values and norms that are shared among a group of people and that when taken together constitute a design for living (Hill). Thus culture is defined as summation of beliefs and capabilities (Tylor), a collective programming of mind (Hofstede) and a plan for life (Hill) (Cited by Fougere, 2007). The cultural norms thus embodied in the collective consc iousness of a people are adopted in daily life in a matter of fact way. These come to be reflected in the work ethos of the business entities. Howsoever, different definitions culture are, there is unanimity of opinion in

Speculative markets, finance Coursework Example | Topics and Well Written Essays - 750 words

Speculative markets, finance - Coursework Example Additionally,the speculator has not to worry of any loss since the American Puts have the opportunities to exercise immediately, therefore will gain access the different values of mispricing at any given time even at its expiration (Shockley 12-45). A synthetic Long call will be created when the long stock position is to be combined with long put of the same series. Therefore, to get the long synthetic stock position for the we assume that; Maximum profit = unlimited The total position of the two individuals will be profitable if the stock is less or greater than $45 or. Such a scenario is known as strangle since the individuals hold two profitable positions to make profits under the bear and bull respectively. The value of a call option is adversely affected with the underlying stock price (in the case $ 390) is expected to drop by a rate equivalent to the value of the dividend on the ex-dividend date. However, as the above case is a call option the owner of the stock receives the cash dividends as of the ex-dividend date, hence the call option can be discounted by a figure as high as the dividend. Therefore, the Amazon call option priced $ 390 and N (d1 ) denotes the probability or the expected value of receiving the Amazon call option at the expiration of option. Therefore, when S rise to $1000 the N (d1 ) will reduce accordingly indicating that as S grows the chances of exercising the option at the expiry date becomes small due to the increment of market volatility for that stock given as 25%. Under this case the probability if decrement of the amazon may be reflected as the 390/1000= 0.39. With the stock value dropping to $50, the present value of the contingent adjusted to the risk becomes less than the exercise price of the option during the expiration date, therefore, making the call value to be zero at its expiration date holding that the probabilities are normally distributed. Ashley can create a bear spread via simultaneous

Case Study on Global Warming and Climate Change Assignment

Case Study on Global Warming and Climate Change - Assignment Example The animals provide the researcher with a great chance to acquire the necessary observation because they allow in making of experimental evidence for causation. The article discusses that there is growing evidence associating the outdoor polluted air exposure with the negative effects that appear in the reproductive health (Somers, 2011). Statement of air quality concern and its relevant to the environmental professional Exposure to ambient air pollution contributes to damage of male germ cells resulting to negative effects on reproductive health. Analysis of the key points in the article Effects of air exposure to human sperms One of the key points that the article discusses is that air exposure contributes in a significant way to the damage of human sperms (Somers, 2011). The author of the article indicates that even though few studies have been conducted concerning this issue, the ones that researchers have performed supports the fact that air pollution causes a negative effect in the reproductive health of both men and women (Somers, 2011). However, results in the areas that the study have been conducted indicates tends to be different. ... One of these limitations is that researchers fail to demonstrate causation of the effects even though it is evident that they occur. However, Somers (2011) indicates that researchers have managed to overcome the limitations using rodents. The animals are exposed to urban and industrial air pollution in order to provide the required results. The direct exposure to the pollution gives researchers a chance to determine the level of effects of sperms. The studies from this experiment indicate that ambient air pollution causes significant effects to many parts of the sentinel animals’ bodies. One of these body parts is the reproductive system. Somers (2011) indicates that a series of experiments on the sentinel animals have proven that particulate matter causes damage to the sperms. Linking the studies of human germ cell to that of sentinel animals Study on sentinel animals provides a chance of having reliable experiment. This is because the ambient air pollution tends to be a sing le variable on the experiment. Therefore, the experiment gives a clear casual links between exposures and end-points (Somers, 2011). Experiments in both humans and sentinel animals indicate there is an induced germline mutation. Moreover, the experiments indicate there is physical DNA damage and epigenetic changes in the sperms (Somers, 2011). However, it is difficult to draw conclusions about the whether the effects of the air pollution in animals and humans are the same. This is because both of them have never measured identical end-points. Conclusion The studies conducted on both humans and sentinel animals indicates there is a high probability that ambient air pollution exposure leads to the damage of male germ cells. The studies indicate that air pollution is

Discussion Questions Essay Example | Topics and Well Written Essays - 500 words - 21

Discussion Questions - Essay Example If one element would be selected for replacement or upgrade, it would be the software system because this is the system that needs most regular updates. This element should be updated regularly to ensure that all applications are being accessed and to be apprised of the most advanced developments that would facilitate the functioning of the unit. A consistent set of policies and procedures that would ensure the protection of information systems in the workplace should include intensifying authorizations to work areas, including access to information systems, through the use of advanced technological breakthroughs in ID checking, monitoring, and access. As such, these policies and procedures should be regularly reviewed and updated to reflect changing conditions in the workplace and to incorporate new technologies that intensify needed protection of privacy and confidentiality of personal, professional and organizational information. In one’s organization, as soon as biometric identification services were offered in the market, this was immediately implemented to strictly enforce security measures as part of the policies and procedures. IT managers, just like any other managers in any organization, could possibly fail when the functions and responsibilities expected of the position and role are not carried out, as required. This included being apprised of current and future trends in technology that would potentially impact and influence the operations of the organization. Therefore, managers must be aware of being too complacent with current operations, regardless of how efficient current operations are. To avoid these pitfalls, these managers must exemplify skills of introspection, information-processing, as well as resource generation and allocation skills that focus on being proactive, rather than reactive. When implementing both technical and organizational changes, some variables that need to be considered and incorporated are scanning the environment
