Rude colleague - confront or ignore?

[UnusuallyLargePelvis]

A colleague recently emailed me to 'pick my brain' on a subject in which I have a lot of expertise.

Despite the fact they hadn't even said 'please' in the email, I answered what I could and told them that the other queries would require me to spend time doing some research. I explained that I was busy at the moment but happy to look into it later.

They have not so much as acknowledged my response, let alone said thank you.

For some reason, this has really wound me up. I've not mentioned anything as I imagine they would take great offence if I suggested they were rude. But, I feel that I ought to say something, in case they ever want my help again.

Am I overreacting?

YABU - who cares, get over it.
YANBU - yes, they are rude and entitled. Tell them.

I'd not say anything, you have learnt something about their character, that is all you need to know. If it becomes a repeated pattern then say something but as a one off ignore it as they may be stressed/busy etc or just not got round to thanking you in person yet.

Royally gets on my tits when people email “thanks”, stop clogging up my inbox, and why are you thanking me for doing my job? .. it’s my job, I get paid for it, that it thanks enough.

Good manners cost nothing. Who would have thought that politeness could be so annoying?

It was not the OPs "job"
The work did not come in via her reporting line, and will not be added into the OPs end of year deliverables review nor will it result in the OPs manager seeing it as contributing to their end of year review.
The other staff member cant be be assed to recognise that the OP made their job easier.

Of course YANBU. I get this a lot in my job and don’t say anything at the time, but tend to be less ‘helpful’ with such colleagues in future. It’s stupid of them as I’m a good ally to have and they waste good will pointlessly. What goes around comes around…

I'd move on for now, but would never do anything to help that colleague ever again.

But that’s still rude. If you’ve read the email. It’s basic manners.

I think you're overreacting. Some go through their emails all together when they've got time. Maybe they're thinking about a response. It's not something I'd sweat about.

you are being reasonable to feel annoyed. But. I’d leave it. Just log their response in your memory and should they ask again just politely decline.

This
Store it @UnusuallyLargePelvis and don't descend to their level.

Is it your job? If not, just don’t do it next time. Don’t say you’re busy, just say no.

It’s rude not to say thank you but surely helping your colleagues is part of your job, rather than a huge favour? If you have a lot of experience then of course you should share your experience with colleagues. I would let it go.

Maybe they’re waiting to thank you after the follow up email which details the stuff you had to go away and research? 🤷🏻‍♀️
