I think it’s pretty commonplace in any organisation that is predominantly male, so it doesn’t surprise me at all, sadly.
I’ve seen it in the local county council, fire brigade, police force, army etc over many years, nothing changes and I very much doubt that there’s going to be any changes in the future.
Get a group of men together and often they turn into misogynistic, showing off, and arrogant idiots, egging each other on.
It’s entrenched and utterly sickening.
