Work Day

Going on personal experience (and those of other co-workers, friends, acquaintances), I have come across an interesting observation:

How many hours during a typical work day do you *actually* do work related activities?

I know that there are the overachievers out there that *only* do work related stuff, but for the most part, I'm willing to bet that most people *actually* only work maybe half of a work day. The other half is spent checking personal e-mail, blogging, reading other blogs, browsing various websites, online banking, etc. And I know that I'm not the first person to ever make this observation, so why hasn't something been done about it? Here are some suggestions that I propose:

~Employees can schedule their own 4 hr work days. As long as one works 4 hrs a day, then all is good.
~Just work 2.5 days a week and then have the other 2.5 days off. (I'm in favor of this one)
~As long as you work 20 hrs a wk, no worries. Any combo of days and hrs will suffice.

I honestly think that if any of these 3 suggestions were put into place at every company, then employees would be more productive! I think I'm on to something here...
