Obviously there are lots of times and occasions where it's appropriate to keep your beak out and mind your own business.
But there are also times when 'not getting involved' is nothing to boast about. We had a serious issue at work recently; everyone was annoyed, everyone wanted 'something to be done' about it etc. However, when it came to approaching management there was a handful of people who decided they 'didn't want to get involved'. Fair enough if they felt they didn't have strong feelings about the issue. But no. By 'not getting involved' they meant they wanted to sit back, keep their copybook clean, and leave it to others to do the difficult work and sort the problem out.
I've seen in with fellow residents as well. The ones who boast smugly about 'not getting involved in disputes' are often the ones who moan the loudest about anti social behaviour but sit back and let the same people approach the management company/landlord/annoying neighbours.
AIBU to think that sometimes you should get involved and support fellow colleagues or residents trying to sort out an issue that affects you just as much as them?
