Anyone else experience gender favoritism in their units?

I work the flightline, 12 hour shifts, and I see A LOT of gender favoritism out there than you'd expect. Females tend to leave earlier 6-8 hours into shift they're gone. No matter how hard they screw up out there the don't get into any trouble because they're just 'learning', and whenever they get cold or something gets to hard for them they just complain, and everyone bows down and gives them a break.

On the other hand, females tend to get BTZ more often because they get more volunteer work down and organize more events because of all the time they have off. They're also expected 1 month per CDC volume when they have 8+ hours of doing nothing at work and I'm expected 1 month per volume working 12+ hour shifts of actual working. Do a lot of you guys see this, and does anyone know why this is? I feel with all the gender equality going on it's not actually showing.

Not going on a rant, just actually giving examples I see within my unit.
