It can be challenging to deal with a manager who acts like Jekyll and Hyde. You never know if the friend or the bully will show up. Here are a few tips for surviving:
Don't take it personally. You may have only said something that triggered a more significant issue for them, or perhaps you were in the wrong place at the wrong time.
Ignore the yelling and listen to what your manager is saying, not how he’s saying it.
Identify triggers or patterns in his behavior. Discover out the cause of your boss’s mood swings — whether it’s low blood sugar, pressure from clients, or something emotional.
Stay calm, and don’t respond angrily; this will only aggravate the situation. You don’t want to say something in the heat of the moment that you regret later.
