Time to clarify something in the workplace. Nobody wants to receive "thank you" emails. Don't reply to emails with thank you. It's just another email to delete and the busy people don't care to be thanked. They just want you to stop emailing them.
@Stevo *nervous glance towards the email to my kid's teacher in my outbox*
@Stevo Unless you don't send them a thank you email. Then they say you're refusing to collaborate with team members.
Thank you.
