The leader promised him a raise, but he didn't take action. What should we do next?

First of all, we should do our own work, we should do our own thing! See if there's anything you haven't done!

Then it is necessary to find out whether the leader promises verbally or in writing. If it's just a verbal promise, you still have to admit what you said, and you have to go to the leader to fulfill the promise in person. Some colleagues are embarrassed to find a leader because of their face, which is not right.

If the leader forgets, he can find a suitable opportunity to tell the story as a joke.

If the leaders pay lip service, don't care, don't haggle too much, and do a good job, the leaders will still get a raise.
