How to Deal with a Nasty Boss

Stand for yourself
Always think about your self-respect. If you are wrong, rectify yourself and do your work properly on time. But if you feel that you are right and just because you have a nasty boss you are suffering his tantrums then do not. Stand for yourself and speak to him about your problem. Some bosses have no idea what actually the problem the employee is facing and they just end up yelling at them. Even some bosses have no idea how they have been treating their employees until employees speak up.
