Know your rights Part V:
Have you considered documenting emails/texts and/or recording conversations with your manager and HR?
Any time your manager or HR sends you a hostile email or text you should retain it on a device that you control (not a laptop or cell phone controlled by MRO). Printing and retaining paper copies is fine too. Not only hostile emails and texts either - save anything that is confusing, ambiguous or evasive or that shows your manager or HR in a bad light. Any of this may be useful if you lawyer up. Does your manager use crude language or tell inappropriate jokes via email or text? If so, keep these. Even if they don’t directly pertain to your situation they can help muddy the water and improve your position against the company.
You should also record all of your conversations with your manager, HR and any fellow employees you feel may be supporting management, undermining your position or hostile to you. Use your own cell phone or other device - not a device MRO owns or controls. MRO company policy prohibits recording other employees without their knowledge, but you shouldn’t worry about this at all. The absolute worst MRO can do to you for violating a policy is terminate your employment- they can’t even confiscate the recording if it is on a device that you own.
Texas state law is very clear - you have a right to covertly record any conversation in which you are a participant. This includes conversations over the phone, in zoom, etc. Texas law prohibits recording if you are not part of the conversation, so you can’t do a leave behind in your manager’s office without breaking the law.
Controlling the record is a powerful tool, as recent police brutality events have shown. Imagine the look on your manager’s face when you produce a recording showing him to be a racist or her to be incompetent?
