Is your boss a little hot tempered? Then you should know how to react when he starts venting his emotions and criticizes you as much as he can. If you already have experience with such a boss, you surly know that it's not worth trying to calm him when his behavior is driven by nothing else but adrenalin. Careerealism.com published a few practical tips.
Don't try to calm him down
No rational requirements work when somebody is under the heat of passion. You parents were right when they taught you to count to ten calmly before reacting to a highly emotional situation.
Don't get involved in arguments
Threats and insults are common in the heat of passion. Don't get yourself be drawn into an argument and if so, never attempt to win it. You'll never win.
Keep calm
Temper tantrums don't last very long. Therefore, stay calm and create your own mental world in which there will be no place for your angry boss. Consider whether you have a choice very well, and - if this should take a long time - start dusting off your CV.
