Even doing this with unrelated parties inside the company is dangerous. The best thing to do is just CC your own lawyer. It's sad, but you potentially open yourself up to liability by warning your co-workers. If you do want to warn them, the best way would be through a quiet, short conversation in a private place away from the company. Possibly your lawyer's office.
I don't see how you open yourself up to liability.
This is before anything is really bad, but you are getting suspicious.
If you hire a lawyer, you're instantly at DEFCON 1. CCing all your teammates has plausible deniability, especially if they're in the same boat you are.
You're not trying to warn anybody here. You're raising a gigantic red flag saying "Hey this is happening to me. If this is happening to you too, let people know instead of just suffering in silence."
> If you hire a lawyer, you're instantly at DEFCON 1.
No, when you hire a lawyer and provide them documentation on what has transpired and is transpiring, you are just building an arsenal to be prepared in case of further escalation.
When you have your lawyer contact the company, even then, you aren't at DEFCON 1, though that is a significant escalation (or a response to one.)
When you file legal action against the company, then you are at DEFCON 1.
If you ever email your coworkers, and CC your boss/fellow employees that you've done so, you're at DEFCON 1.
That implies that legal action is imminent.
If you BCC your lawyer, or just save up the information for later, that doesn't escalate the situation quite as much and allows people to back down more.
