I work in a place where the age and sex of the employees fluctuates annually, so here's my observations...
When we have:
-mostly younger women working, there's a shitload of drama and general immaturity. On the upside, work gets finished in a quality manner.
-mostly younger guys working, than little work is completed, or there is a "macho" competition vibe going on. On the upside, when work is finished, it's in a timely manner.
-mostly older women working, they're usually on a power trip, enforcing ridiculous rules and making work feel uncomfortable and stressful. I still haven't found an upside.
-mostly older men working, it's usually more laid back but the superiors are clueless how the company really run, on the customer level. I guess that's just how a bureaucracy is, though.
Can never win.
