Surf the net, check your e-mail, whatever, when you get home from work!
I think the key words here are "when you get HOME". The problem is they are contractors and don't go home. I myself go to the local library when on the road. However if it's closed, because of the time, you're out of luck. It would seem that the use of the internet is a small thing, as long as it's not abused.
Back in the day I can remember the rent-a-techs using the phones for hours. Then the utilities wanted to ban the use of off site phone lines, now everyone has cell phones. If you don't abuse it, I just think it's a nice thing to have available.
As usual, just my opinion, I could be wrong
