4. Never tell your boss that this is not your job: You are sure to lose your boss’ support if you tell him/her that, this was not mentioned in your job description, therefore you can’t do that job, assigned to you by your boss. Keep in mind that job descriptions are not comprehensive , so, most professionals today end up doing work that were not mentioned in their job description, but they do it in order to be more valuable in the organization, and remain ahead in the company by being on the good books of their boss. If you every time claim that this not your job then your name is sure to be there at the top of the organization’s lay- off list.
