Rude colleague - confront or ignore?

On work emails we are encouraged to not say thank you electronically, due to the impact on IT servers and energy use. Maybe this is their thinking?

We’re encouraged to do it in person which is fine for us as we all mostly work in the same office so see each other quite frequently but it is difficult when you don’t see someone in person for ages.

I’m gradually getting used to it, but it does feel rude and terribly unBritish.

Not worth a second thought.

This is such a minor annoyance. Yeah, maybe mildly rude but it’s hardly a big deal, surely? I probably wouldn’t even have noticed the lack of thanks, and if you were busy, why would you want another email to open anyway?

This is the kind of thing that happens a million times a day in the workplace and really such a non-event that I’m amazed you’ve devoted more than a speck of headspace to it.

Make a mental note not to help them if they ever ask again. And I agree with the PP who said act all surprised if they get back to you, asking for something else. Bloody cheek, it is rude.

It’s incredibly rude of them, but YABU to want to confront it - it won’t achieve anything or end well.
Just take the whole thing as a learning experience. They have shown you who they are. Next time they need help, you’re too busy, sorry.

I would forget about it and move on. There could be lots of reasons they haven’t acknowledged your response, some of which may be perfectly understandable. Some people work on different timeframes etc.

I would however not be ready to be so helpful in future should they want to ‘pick my brain’ next time if they never acknowledge your response.

I think you're overreacting. I don't see how it matters or how it has hurt you. If you're a colleague, surely it's expected for everyone to chip in where they can so everyone's jobs are done properly?

In your shoes, I'd be flattered that someone thought I was a good person to ask or that my expertise was valuable to them. I wouldn't need additional pleases and thanks. I feel warm and fuzzy enough that someone reached out to me specifically, it's a compliment and gives me opportunity to show off my knowledge. I love it when colleagues come to me and I can help.

Disclaimer: awaiting autism assessment. I understand now that the way I see things is not necessarily the way the majority apparently do.

If you said you was busy I wouldn’t then send a email saying thank you as you’ve just said your busy so taking your time to read another email when your already helping me, I would assume is taking the piss a bit.

Im sure they are grateful for your help and will probably say thank you later, when you’re less busy.

Very rude.
I would not put myself out for them, nor would I add to the reply you have sent.

I wouldn't tackle them on their rudeness I would just adapt my behaviour and match their energy.

It takes a nanosecond to respond saying 'Thanks for this, appreciated - will be back in touch if I need more info'. To ignore a detailed reply is just plain rude, no matter how busy someone is. Very rude also not to say please if asking for a favour.

I think I would say nothing for now. However, if they get back in touch about the outstanding queries I would be tempted to act faux surprised. " Oh, are you still interested in this ? Given that you didn't acknowledge my previous response I assumed it was of no interest so I haven't taken it further."

I'd go back to them before you do anything more and ask them have they had chance to read your initial response and say you're really busy, but they can go to x website, etc to find out more/the specifics if they need it quickly. You can then decide what to do depending on the response.

They may be busy themselves or digesting what you've sent before responding.

Was it work-related, it’s not clear from your post?
