I can see their screen, they are on facebook, instant messenger, shopping, web surfing and constantly on their smart phone (which I guess is more obvious than web use on their screen)
My company has a relaxed attitude to web use as long as we get our work done. I also realise I am on Mumsnet and so not working for the time it takes to post this.
But this is a total other level - and it's everyday.
I am not their manager, not responsible for their work and so am ignoring it....but what would you do?
