| It is a poor manager that mixes friendship with business to the detriment of other employees.
Well first, you must find the courage to defend yourself when the person lies to the manager. The boss may simply mistake your not fighting back at all as an admission of "guilt". Don't yell or shout. Simply say, firmly, "that isn't true". Be ready to say why it isn't true. Remember that you are defending your job.
If that isn't working I think you should have a closed door session with the manager to address your concerns. Be cool, be professional. Do not attack the "friend". Put the discussion in terms of your being concerned that the colleague's' comments may have left a wrong impression, and you want to clarify things.
If you do not get a positive response, you probably should start looking elsewhere for work, if for no other reason than your boss is a jerk. But...there is one other thing to try, if you think the situation warrants.
If your boss has a boss, and your boss does not give you a good answer, it MAY also be possible to express your concerns at the higher level, and get resolution, but that depends on the dynamics of the company, how well you are known, etc. Even if you get resolution that way it may cause ill feelings that will fester.
Either way, you have to find the courage to resolve the issue, as things will not likely get better otherwise
Good luck |
