Except for the military.
I once interviewed for a job at what I think was a civil service branch that developed software for the military. But they were out of budget for this, while the military did have budget, so if I was hired, I'd have to wear a military uniform to the office. A very stylish one, they claimed.
Just like Dutch military air traffic controllers, they sit in the same building as the civilians but wear a uniform and get paid less.
