I just want to know if I’m being unreasonable? I work in our little family business & I’m getting rather pissed off with my SIL! I do a lot of heavy lifting & picking orders but she swans in & sits down on her arse at the computer doing not a lot! She doesn’t even bother asking if anything needs to be done, yesterday after putting stock away my DH asked me if I was going to make us all a coffee he was serious too! I saw red & told him to fuck off & ask his precious sister instead, he would rather upset me than his sister, so I’m in today & yet again lifting & carrying whilst she sits on her backside claiming to be soooo busy. I’m in a t-shirt & she is sat there in big coat & the heater on! I’ve already told my DH I hate working there but he takes very little notice of me in general!
