As an outsider without intimate knowledge any of this could be wrong, but, I’ve been on both sides of the tech and manager relationship and: - there’s a clear problem in how the news that you’d be signed up has been delivered: they haven’t done it at all and of course that causes you some negative feelings towards the whole thing. So they should have done better. - he may not know you didn’t agree to it, he may not know you don’t know the system. He may have just been told “roll out this new on call schedule to everyone”. - if I were you I wouldn’t assume malice, I certainly wouldn’t consider quitting without further discussion. I would arrange to meet your manager that you like and explain the situation - what you’ve been signed up to, why you don’t want to and are stressed. Then from that you may need further discussions with the new manager as well. Either they get you trained up to a comfortable level and feel bad for the terrible delivery, or you find out they don’t care or are pushing you into something you don’t want to do and at that point perhaps you know is time to leave Good luck
