I work in a relatively small, close knit team and about 6 weeks ago, a new team member started. He's not my type of person but he's pleasant enough.
He sits diagonal to me so he's directly in my vision from behind my monitors so I see that he basically spends all day on his phone - not just checking the odd message or whatever, but constantly on his phone and it's pissing me off no end.
I had cause to use his machine remotely the other day to test something and I left his screen up (this is allowed in our work before anyone starts having a go about privacy) - basically I saw that from 12pm to when he left at 4:30pm, he didn't do one bit of work, he was just on his phone and looking at newspaper websites - I'm not exaggerating, he didn't do anything, work-related, for the whole afternoon.
His work doesn't affect me, in that, if he's not doing what he should be doing then it doesn't directly affect me but at the same time, he's in our team and I feel he's taking the piss out of the rest of us and our manager. He's still in his 3 month probationary period.
I've moved my monitors to try and take him out of my direct line of vision but I can still see him and it's annoying as hell. Should I just mind my own business or should I do something about it?
