This is going to sound ungrateful, but dear coworkers, don’t thank me for doing my job.
If I send an email that I cc’d you on for paper trail reasons, don’t reply with a ‘Thanks!’ – you’re clogging up my inbox. I don’t need verification that you received the email, you sit three feet from me, I heard it arrive. Whether you read it or not I frankly don’t care. If it requires your action, I’ll follow up when needed.
A lot of my daily tasks include the mundane minutia of just doing my job. Stop thanking me for those and please stop thanking my coworkers too, you’re setting a bad example that they expect praise for doing what is expected of them. It makes true praise meaningless, and admonishments are obscured by all the fluff.
If I save you from a burning building or rescue your puppy, by all means, thank me, but I don’t need your constant acknowledgement. I know I’m doing my job and doing it well. And guess what, I’m not doing my job for you, I’m doing it for my community. They thank me and that’s enough. Your appreciation in these matters is watered down and hollow. Your Thank You is not welcome.
Edit: I have something to add to this – I recently received a huge thank you from about a dozen of my fansite owners. Their thank you was welcome because it was genuine, and came from a place of true community not of corporate duty. Know the difference and your thanks will be welcome.
