How to ask the leader about the salary increase?

In fact, such a question is very simple. If it is a state-owned enterprise, you can ask casually: Manager X, when will we get a raise? If it is a private enterprise, it may be a bit abrupt to ask. We can find an appropriate opportunity to say: boss, it doesn't matter if you are a little tired. As long as the boss can give us a little salary increase, then we are not afraid of being tired. Although you tell it as a joke, the boss will never listen to it as a joke
