My employees are accusing me of being unapproachable, not allowing input, being moody, and raising my voice in one occasion. These allegations are coming AFTER I told the group I would hold them accountable for repeated mistakes and told them to look up answers on material I had distributed before coming to me for questions. I have stacks of emails proving that I have been a caring, flexible, and fair manager to them. I sense bias on the part of the Human Resources VP. She told me that "perception is reality" and that my employees were "afraid of retaliation" and that she would have me sign a document stating I had received these allegations. My follow-up meeting with HR has been scheduled for next week and I'm prepared to submit all the evidence on this matter. I don't want to sign any documents and not have HR take into account my side and evidence. Please advice. I live in South Orange County, CA and work in Los Angeles.
