I do genuinely love my job. Having distractions such as this makes the day go quicker & I only come on here in bewteen real work, but I have never said my job was boring.
(Although if I had my time again, I would go into a different profession, even though I have done relatively well at this one.)
FB is blocked on our company network, as are several other sites, though we are more concerned in a lot of cases at staff using company bandwidth which causes a knock on effect and slows down use of legit sites for genuine work reasons
