I also say “thanks for the update” or “thanks for the head’s up!”
“I really appreciate the head’s up!” also a classic
If I haven’t gotten back to someone in a swift enough period (i.e. one work day max) I say “thank you for your patience. after some consideration, I have decided…”
don’t apologize for piddly things!
thank you > sorry
I need to remember
thank you > sorry
Thank you for waiting for me > sorry for being late
Thank you for helping me/for your time/for listening to me > sorry for bothering you
Thanking someone when they do you a favour > apologizing for your existence
This is especially hard when you haven’t been taught that people need to respect your limits, but with a bit of practice you can absolutely get there!
I really want to emphasise that from unfortunate personal experience, being too willing to apologise can fuck you over in the workplace - it doesn’t matter how much of an honest, good person you are, if you are the only person regularly admitting fault and apologising for mistakes … you may well end up with your workplace having the impression that you’re the only person there who fucks up constantly. Even people who like you can end up thinking it. Don’t let that fucking label happen. Say good catch and thanks for telling me and go forth with your ass firmly covered instead.
