I work in a environment were the turnover is high. So I'm used to all sorts of people and not easily offended. However new person is quietly annoying me. They are very efficient and are keen to get stuck in. Can't complain in that area. However it's the little comments that are starting to wind me up. I've started to sigh deeply when they say something annoying but I will bite soon. I'll give a example. A machine didn't work I asked the boss what was happening. She replied oh I think you opened it too soon. Annoying colleague (A.C) said "oh no you've broken it, what you like!" Another example i was passing something to A.C and it dropped they said " oh no, your throwing it at me!" Another example I was looking for something and couldn't find it they could have helped bit instead said " oh no what you like, can't you find it! Maybe you've binned it" offering no practical advising it help. Writing it down it seems so simple and a non event but it's at least 2 comment a day. It's almost a form.of workplace negging maybe? Or a way to make me look bad in front of the other colleagues. When they have misplaced something or needed showing something I just did it. Didnt make a big deal of it??? So wise mumsnetters hot any advise on how i can stay sane in the workplace and not let them get to me. I appreciate there are bigger problems but my God its really bugging me!
