At one point I worked for a large telecom company that did something like this. You had to log bathroom time because they found out people were spending four to five hours a day in the bathroom. It was ridiculous.
LOL My husband has Dilbert on his phone, and we go through all the old ones a bit every night, and as soon as I read this one, it just reminded me of my old job. :p Not a desk job, but seriously, if you wanted a vacation, you had to sit on the toilet. :p Well, or just not have a paid vacation b/c we didn't get anything like that. lol So, I found this VERY amusing! :D
I worked for a company that got angry about the number of times I went to the restroom in a given day. It was a water-softener company. They were also upset that we didn't drink much water.
