How to reply to the congratulatory message sent by the boss

Well, I don't think it's necessary to be so nervous about this. The boss is congratulating him on his success. (The boss is human, too. )

I think it's natural to reply to text messages. If you like your job and your boss, you can: thank your boss for his information, and then show your determination to continue working hard. Or talk about the difficulties or gains you have encountered in this job.

In short, it is to reply to a message that makes people feel sincere.

Ps: It's just a personal opinion. If you don't like it, just pretend I'm talking nonsense here.
