No, and I'll prove it with a simple example:
Consider a population where there are a million workers and all of these workers except 78 are female.
Now we apply the layoff such that all 78 males plus 22 females are laid off; this has *eliminated* the entire male workforce in this scenario, yet it is still true that “78% of jobs lost belonged to men.”
QED
But that’s not the real world. That would be like if the NBA eliminated some franchises, someone could say, well that’s not fair, as 80% of the “layoffs” were black. In a male dominated workplace, layoffs are going to be disproportionately male, especially since they occupy the highest paid positions. In order for layoffs to disporportionately affect females, they would have to occur at the admin/nursing/teaching spots, etc where females tend to dominate.
