Is there a good word for describing "a request that cannot be refused"? For example, the context I'm thinking about is a situation where your boss "requests" that you work overtime one day, but it's pretty clear that it's a request that can't be refused (or, at the very least, it's something you believe you can't say no to).
I guess we could say "irrefusable"? But I'm not sure if that's even the right word, and I'm wondering if anyone can think of a better word for this.
Thanks!
