Manager has been causing trouble in work. Telling different staff of other members of staff are telling her in confidence. She's told me stuff about certain staff members of what they've said in appraisals.
She's accused a new member of staff of going out with the others when she didn't but seems to have a big problem with this. Saying she finds it's weird that she's been told she was going but didn't.
Has been going between said member of staff above and another causing trouble between them but making out like she's trying to save new staff job. Eg "I'm the one that's saved you from getting sacked, everyone wants you gone"
Member of staff is off with Covid but the others are out tomorrow for a few drinks she has messaged another member and said "I'm telling you now if any of you out with her tomorrow and get Covid I won't be happy" this
Member isn't even going out.
She shouts and swears from her office to us.
She's passive aggressive with everything.
We all want to report her but don't know how to go about it. The people above her seem to like her I think as she is good at her job. Some of said we all need to get together with what she has done to each of us and then go above her but we're scared that it will come back on us.
Any suggestions?
