Ok, serious question: what is the course here? Can you be forced to swear?
Generally speaking, you will be asked to swear or affirm that you are going to tell the truth, and that you understand the consequences of not telling the truth. Whether you do a whole ceremony about it or not, it doesn’t really matter – but the court will want to know that you are competent to testify truthfully and that you know that you’re not allowed to testify to things you know aren’t true.
If you’re asking “can you be forced to testify?”, the answer is “Yes but it depends.” If you’re competent to testify and the officers of the court deem your testimony important, they can subpoena your testimony. If you have a reason to contest it, you can – but “I don’t want to” isn’t good enough.
If this happens they’ll do the “A person who swears to tell the truth and nothing but the truth says what” ordeal. If that doesn’t work they will just let you leave
“Anything you say can be used against you in court.”
“Titties.”
“…”
Held against you. It works much better with the proper wording.
I once crossed off something I didn’t like on a contract and the boss scolded me and put a fresh new one in front of me while printing out yet another one.
All contracts are negotiable, you did nothing wrong other than not having a conversation before wasting paper, the main issue is that for most people the negotiation is “if you want to work here you have to agree to all this.”
But yeah reasonable accommodation and mutual understandings, etc, should be written down and signed. I challenged the non-disclosure agreement at my job once because it literally said I couldn’t talk about my work with ANYONE, and a plain reading of it would mean I’d be unable to even talk to my boss about what I was supposed to be doing. It was poorly written and probably unenforceable. My boss didn’t like that so I signed it anyway and then focused on finding work elsewhere (he was a dick and his company got raided by the FBI a few years later)
