That won't help the company if the law has been changed to set a 30 hour maximum, which is my point: Why are you generally not seeing electoral support for 30 hour maximum work weeks?
From my current boss, and sadly repeated by a significant number of coworkers, "Because our competition is working more than we are. If we don't work these crazy hours they win."
To add insult to injury, this particular employer is the least efficient place I've ever worked. I'd estimate the average employee works 70-80 hours a week, but 1/2 to 2/3 of that is simply working around poor management or fixing mistakes that could have been avoided.
So, when I seek to get my fellow employees to consider the possibility of working toward a 30 hour workweek, I get the "our competition" argument. When I try to introduce efficiencies, I get the "we don't have time to learn/employment/etc." arguments.
Sadly, because of the economy and commitments I have, I haven't been able to find another job that I think is enough of a good bet. As soon as I do, I'm outa here!
