I'm with you, but if you're paid on the hour, 1 hour paid to read a gaming website is not a really good investment in the eyes of a boss.Why would a work place block gaming sites? I mean if the work gets done then what's the problem?
But I totally agree : if letting off some steam (pun intended) from time to time makes you more efficient at work, then it must be seen as a good investment.
In the eye of bosses, the problem is that they're 100% sure some people can't help themselves and will neglect work to do "anything else, having fun instead of being productive while being paid".
Or maybe think that if you're able to do all your work in 6 hours and pass the 7th on a gaming site, they should only pay you for 6 hours and let you go home sooner.
I met a lot of bosses that thinks that way.
For the record : I'm writing this while being at work on a paid hour.
