Team bonding became a lot more interesting, when they put the first female on my shift.
I'm surprised you noticed if you were working in IT

I was surprised when I found out that the other 2 shift leaders had said that they did not want a female on their shifts.
It was some time before I found out that it was illegal for
a) a sixteen girl old girl to be working a night shift
b) a female and a male to be working alone at night in a building (there was a caretaker but apparebtly that did not make any difference)
And yes I did notice, particularly some later when her and by then another female op, came onto the night shift (12-8) wearing hot pants and thigh boots.
That was a long hard night.
