to be annoyed at my boss

[NicknameTaken]

There's an upcoming work trip to South Africa. We have a small team, most of whom are going. I said I was willing to go if needed. Tbh, I didn't want to, because I have DD(2) and would rather not be away for her for 2 weeks. It would be a sacrifice for me. I never once said that or mentioned in any way that it would be awkward.

My boss decided to make alternative arrangements for someone else to go. I'm happy with that. However, he also reprimanded me for my lack of enthusiasm about the trip. Apparently I should look on it as a great perk of the job.

Is this fair? He's reproaching me not for something I did or failed to do, but about how I felt. Something he perceives as a perk does not feel like that to me, but somehow my feelings are "wrong".

I haven't been penalized in any formal way, and I'm not about to rush off to an employment tribunal. I just hate that my boss (usually a decent person) thinks less of me because of this.

So I'm not AIBU by stealth, some factors that may be relevant: boss doesn't have dcs, and neither does anyone else in the office, although his wife is pregnant. I could leave my DD with my exH, but I'm reluctant to do so (I have some concerns about his parenting but he has a lot of access to her due to a court order). The trip is not related to my main work duties.

My home life shouldn't interfere with my work, I fully appreciate that. I didn't ask for any special accommodation to be made for me, and it is helpful that my boss did it anyway. I should be grateful, I suppose, but damnit, I'm annoyed to be accused of having an attitude problem when I was willing to conscientiously do something that was difficult for me. So AIBU?

he umm sounds like a jerk, your boss that is.
You said you would go if needed and it sounds like it would have been hard for you to go so in fact i think you showed commitment.
Also i think it's rubbish about homelife interfering with work life. Yes you need to balance it but also your work should aim to balance their demands on you. They employed you as a whole person and with the comes a whole host of committments that you have. Those committements and that outside expereince gives them benefits which go above and beyond any job description. Sorry stuff like this really gets my goat. While making me relaise how very lucky i am to work were i do.

Not unreasonable at all. Unreasonable of your boss to assume you'd share his enthusiasm.

no yanbu @ all!

YANBU, he sounds like an asshole. PLenty of people wouldn't fancy a 2 week work trip for loads of reasons. My husband hates travelling with work and always has even before we had kids. He will do it but is never jumping up and down about it and certainly never regarded them as perks of the job. How unreasonable of him to think people should have the same view as him.
You have acted absoloutly reasonably and he sounds like he is just finding fault.
As for home life not interfering with work life this is not the case here at all, as you were prepared to go. If anything it is work life interfering with home life.

Thanks for the verdict, MN jury! I feel vindicated. I used to have a lot of goodwill towards my workplace, but this has gone some way to squandering it.
