In my previous job, I was the first person on my floor to arrive at work one Monday morning, and went to open the window nearest to me, as it was a rather muggy day. However I could only open it about an inch-and-a-half.
I thought maybe the window was jammed, so spent about 5 minutes pulling and pulling at it, with no luck.
In defeat, I thought I'd open another window, but the same thing happened. I tried other windows, all the same.
At this point I was utterly bemused, as when we'd all gone home on the Friday, the windows had been fine.
Then someone from another floor popped in to drop something off for someone, and she laughed at my confused face, and told me the new management (the company had just been taken over a few months before) had ordered the modification of all the windows so they could only be opened slightly. This was to "avoid accidents or other distressing incidents."
I assumed by other distressing incidents, they meant to prevent anyone jumping out of the windows, which isn't really a good selling point for a company is it? "Our windows only open a fraction, to stop our staff jumping out the windows."
Seriously though, everyone thought it was utterly bonkers, and it meant we spent that summer sweating like pigs (we had no air conditioning, as it was an older building, and it wasn't economical to put AC in).
A new rule got added to the company code of conduct, which was that anyone who modified a window or windows themselves, so they would open further, would face disciplinary action!
They brought in a few other bonkers things too, for example we had a subsidised canteen, and to apparently save money there was a notice one day that said "you can now only have one filling with jacket potatoes." However, in the past, if you had two fillings you obviously got 'half and half', so you got the same amount of filling as someone who had one filling, it wasn't as though you were getting whole servings of both fillings! None of us could work out how banning 'two fillings' would save money! 
I had gone back to work there part-time after my DS was born, but the place had become such a joke to work for, then when I found out I was pregnant with my twin DDs, I decided there and then I'd not go back and would WAHM instead.
