Glad you said it. Now I don’t have to.Its not a 4th amendment violation because it is NOT the government asking you to do this, its a company so you have no bill of rights other than what they grant you there. They can tell you what you can and can't say and can read your company email and search your company computer and listen to your phone calls made on their phones and make you pee in a cup if they wish.
OP, you have no 1st amendment rights on my property. You don’t have any 1st amendment rights on this board. The even have a sticky for it. Private property means the owner has the rights. Anything the owner let’s you do is a privilege.
Misunderstanding the constitution is as bad as being against it.
