Is this a case of enforcing strict work hours and conditions as a "performance management" technique to ensure employees aren't slacking off? I imagine it is difficult to know whether someone in a creative job has actually performed as much work as they claim to have done. The other plausible reason for strict work conditions that comes to mind is for highly collaborative jobs. Jobs where you're not paid to work on your own and produce result X, but rather, you're paid to be part of a team, continually bouncing ideas off each other to produce result Y. I guess it would be similar to pair programming -- with more than 2 people involved. Other than the reasons above, I can't see much reason for forcing people to work in a strictly-enforced rule-based workplace. Have I missed something?
