What should I do if I meet a colleague who loves to curry favor with the leader and is lazy?

It is very annoying to meet such a partner. You have to do a lot of work for no reason, especially when you work very hard, which will make people feel unbalanced. But don't care too much about this person. You should know that a coin has two sides. He brings a lot of trouble to your work and affects your work mood. Do your job well. I have a female colleague who is like this. All you have to do is be more professional than her, but you don't have to do everything. Do whatever you can.
