<prompt> Human: I was given a 9k salary increase 2 weeks ago to start Dec 1. Employer didnt mention that is was to comply with the salary increase law. Now that the law is postponed what might happen?Assistant: They could always come back and say that it was related to the salary increase law change. Then they could reduce it back to where you are now. If they do that, time to look for a new job.Human: I have a signed letter from the COO that i also signed and submitted to HR that lists the new salary. Does that make it harder to reverse the raise?  <response>: Arguably, but if they choose to go back on their word, nothing is stopping them. Same issue if you quit on December 2nd because you found something differentbetter.
