I don't know if "They're better at hiding it" is sufficiently negated by responding with "I've never seen it."

Also crying isn't the only form of emotional breakdown. It can also get sublimated into rage which manifests as screaming at subordinates, punching walls, road rage incidents, and domestic violence.

And it also sublimates into depression, which can manifest as substance abuse disorders and self-harm.

I think the OP claim that women are incapable of handling the same workplace pressures as men are is eliding a lot of information.
