Hi all, not sure if this is the correct place to ask about this, but I've been working for a US company remotely for about 3 years now and they have today decided to add on a weekend on-call rota. Problem is that we are all against it and it's not outlined in any documents I have. It would be 2 additional 12 hour days (weekend) every other weekend, being available from 5am to 5pm, but with no extra pay or time off in lieu. On top of that we're expected to use our own devices to receive notifications and calls.
I'm not sure how this works in the US, but I'm pretty sure over here it's not something they can enforce without proper consultation with HR, some kind of payment, and a legal contract agreed by all parties. At the moment it's been a team teams call and a rota (which we have to manage ourselves too).
From a legal standpoint do I have to agree, or am I right to refuse the extra work and just work my contracted hours? If I refuse can they terminate my contract?
Edit...I'm in England here.
