上司 (shàng si): boss; superior

My boss is very strict about work requirements, but privately cares a lot about us.

Tomorrow at ten in the morning, I need to report this quarter's sales situation to my boss.

Because my boss suddenly arranged a business trip for me, I had to cancel my weekend travel plans.

As soon as he was promoted to department boss, he treated everyone to a meal to thank the team for their support.

If you have different opinions about the project, it's best to communicate directly with your boss instead of complaining behind their back.
