Working overtime
If I recall correctly Uncle Bob has a good story about IT, where they had a team working after hours to deliver a software on time.
They eventually did it, and to make the schedule it was needed that legal do some after hours work too, and someone came to Uncle Bob and said that it wasn't going to happen, because those people were professionals.
As in, IT guys are just kids, and the other professionals can't be bothered to work extra hours or weekends.
In my (albeit little) experience with IT, we as a group should cut that sort of stuff out.
I mean, I can work weekends and answer phone calls in the middle of the night, but you better be ready to pay me extra for it.
