Employment Law Questions? Ask an Employment Lawyer.
Good evening and welcome. I am sorry to hear about this issue with the interim GM. If I may ask, what exactly is your question regarding this situation?
I very much look forward to helping you on this matter.
Thank you for clarifying. It may be "harassment" in the dictionary sense of the word, since it is unwelcome conduct, but it is not illegal harassment. Harassment is only illegal if the conduct relates directly to a legally protected trait, such as race or religion. Things like yelling racial slurs at an employee would be actionable harassment. But what you describe is more accurately described as company politics. Company politics can be frustrating, even downright infuriating, but these sorts of things do not violate the law or give rise to any legal basis for a lawsuit. They are things that can only be dealt with on an interpersonal level--the legal system will be of no assistance.
So, all you can really do here is attempt to reason with the interim GM that you did not engage in the conduct you have been accused of. You are not in a position of legal leverage, and this is not a case where the best defense is offense.
I hope that you find this information helpful and am genuinely sorry if it is not what you were hoping to hear. Please do not hesitate to let me know if you have any questions or concerns regarding the above and I will be more than happy to assist you further.
