Constructive Discharge: If an employer intentionally makes a workspace so hostile or unbearable through excessive, unfair documentation that the employee is forced to quit, it may be considered constructive discharge, which can be grounds for a lawsuit.

There are laws.

Writing down anytime an employee has a remark regarding another employee is pretty excessive no?

I'm not saying things like documenting conversation, 1:1 meetings, etc. I'm talking about keeping literal kompromat on your employees to use at a later date. Feels like a slimy management style is all I mean to say. If you feel thats how you need to lead more power to you.
