It's probably culture-dependent and I'm not American.
Being 'pushy' or 'tough' sounds nicer, but it's different from shouting and throwing tantrums, which seems to be the case from the descriptions.
Pushing employees to excel, if you're careful to be reasonable and push in the right direction, could be okay.
Throwing tauntrums just seems unprofessional to me, and seems like it will make people quit, especially the ones who actually have social skills.
