When you first start working, you may be getting a feel for corporate culture and trying to decide if you really enjoy the job you are doing or if you want to adjust your career focus. Sometimes, real upward mobility is achieved by moving from one company to another. Staying at a job with no opportunity is one of the common career mistakes that people make. These questions can help you determine how long you should stay in your current position. If you do leave earlier than that, you need to have the reason why clearly labeled in a positive manner so that you can handle any questions you get about it. If you are only six months away from being vested, it may be worth waiting until you hit the length of time to keep those contributions. Many companies will have the cut off at the five-year mark, but some companies may consider you vested after three years. If you have two more years before you are vested in the plan, it may not be worth waiting to look for a new job. You need to find the balance for your situation. However, if you have been passed over for a promotion, you may want to start looking, because your management may not see you in a leadership role. You do not want to spend time in a position where you are not valued and appreciated. If your current employer paid for some of your college classes through tuition reimbursement, you may need to work a set number of years with your employer. Create a solid plan so that you can reach your career goals. You should also try to save up some extra money to cover yourself as you switch over your benefits between jobs. You may also decide you are willing to downsize to take a job with less stress.
