'[I] asked for a 15k raise': Hybrid employee pressured to come into the office 5 days a week, employee refuses to give in without his promised promotion

Let this story serve as a friendly reminder to stand up for what you were hired for in the first place. If your boss tries to impose new rules and regulations, new responsibilities, and new expectations that were not expressly written in your initial contract, then you are well within your right to advocate for yourself. That means advocating for a raise or promotion if you feel compelled to do so. It can also mean enforcing what's currently written in your contract if you do not wish to accept the new changes. Be prepared to receive some pushback, of course, but again, you have some leverage here.

This hybrid employee was hired with the expectation that he could spend two days working remotely, which was convenient for his family and young kid. When his boss suddenly decided to adjust those expectations and demand that he come into the office five days a week, the employee stood his ground and said he would only do so if he were granted a 15k raise. This led to a difficult negotiation process, but folks like us are proud of the original poster (OP) for not backing down.
