I've had one boss who was a screamer. He'd have cellphone conversations in the office and be screaming at vendors and staff. It was a passive way to say 'You might be next.' At first you kinda can't believe it because it's so fucking juvenile and then you realize – shit I've gotta get out of here. It is never ever ever ever ever worth to lose it at work. You're not Steve Jobs. Go sit in a bathroom stall and breathe or cry until you're done.
Shouting is less tolerated in the workplace these days. But our new ways of fighting- such as sharp emails- aren't always healthy.
