Personally I feel a door ought to open both ways. If I put in long hours and weekends to meet customer commitments, the company ought to allow downtime during slow periods. A text forum is not a bandwidth heavy site. Bandwidth is what costs the company money directly and affects other legitimate users on the same pipes. Of course if the internet usage policy needs to be implemented strictly, then it also means a strict 40 hour work week irrespective of deadlines. Any slippages will need to be replanned and nobody in the team will feel motivated to go beyond what is expected of them. This is my opinion is a larger productivity nightmare during a live project than lacking productivity during no projects. Just my 2p.
