You just got off work, and you are already dreading tomorrow. In spite of putting in a constant effort, management or co-workers still treat you badly. You spend the majority of your adult life at work, so you should get a job that makes you feel valued and respected. It is often a difficult decision to leave a bad job for a new one, but if you feel unappreciated at your current employer, it may be time to find another one.

Speak to your supervisor first about leaving. Never tell co-workers you are leaving before you inform management. You do not want them finding out through someone else. Provide clear reasons why you think they treated you badly. Give examples of when you think you did not receive fair treatment. Your current employer will probably ask why, so you need to have a definitive answer. If they offer to try to remedy the situation, inform them you already have another job lined up.

Give sufficient notice that you are leaving. Give at least two weeks’ notice to your current employer, unless you experienced harassment or there is other misconduct occurring, including discrimination or physical abuse from a co-worker. Many companies expect a resignation letter if you are going to quit for any reason. Include your last expected day of employment, your contact address and phone number and your signature. Hand this to your supervisor when you give notice.

Offer to teach the person who will be taking over your job. According to U.S. News & World Report, if you have time to train your replacement it is a good idea to stay long enough for the transition. In spite of poor treatment, it will be difficult for your current employer to criticize you if you were generous before you left.

Keep all of your current commitments to your employer. Someone else will be taking over your job when you leave, so you want her to be impressed with your professionalism and organization. You never know when you need a good reference or if you will want to return.

Don’t talk badly about your current employer with co-workers. Negative comments can spread throughout an organization to higher management. Maintain your professionalism--a poor attitude will only sound unprofessional and petty.

Concentrate on what is best for you. According to CNN Money, if your boss and co-workers do not like you and you are getting stuck with work that no one else wants, these could be indications it’s time to move on to a new job.
