Supervisor response left me frustrated how would you reply?

Your boss is clearly not doing her job; she states: "I cannot guarantee this person won't do that again" well, hello! That is what bosses DO, that's what separates them from the rest of the employees. She is too passive and clearly does not want to involve herself which may also be a fear on her part and a desire not to upset this harridan. Also her comment re "life's not fair" is so puerile I can;t believe she said it and that she's the boss of anything. She is clueless and spineless and you need to go to HR for assistance since all your boss is willing to do is listen and spout pointless cliches and not doing her job.

Mr. Boss, you appear to be approaching this issue as if it is a personality clash between two employees and nothing more. It is more than that since the other person is expressing his anger issues while customers are present. It is disruptive in a way that harms the business; customers are our lifeblood and our purpose for coming in each day.

While I respect your position and your decision, I also am loyal to the company and it's needs. While I really do not wish to go to Mr. YourBoss, this issue is such that it must be handled as the company is suffering because of it.

I would like to stress that I have no issues with employee; I am not trying to stab him in the back or anything like that. I have tried talking to him myself in a friendly manner to no avail. It is a management and HR issue that is above my paygrade. If you like I can provide you with the names of some customers who can relate to you their discomfort during his temper tantrums.

Wow sounds like you should be the supervisor. Your boss sounds very incompetent. Anyway to answer your question I would simply say, "yes but shouldn't we at least try to correct this behavior? This is very unprofessional and disruptive? Maybe if this (co-worker) knows the repercussions he/she will stop this behavior. I believe this person really needs to be spoken to" - something like that. That is crazy. Good luck.

Your Supervisor basically let you know that he/she wasn't going to do anything to stop the behavior. So why push the issue? Just let it go. She/he was right, life isn't fair and sometimes you just have to roll with the punches.

If you're going to complain, don't do so from the perspective of how it affects YOU. Do so from the perspective of how it negatively affects the organization.
