First, Careerealism.com recommends trying your best to grasp the situation. Your attempts to calm your boss down and rationalize with him or her are likely going to prove useless - this is what comes with working with a hot head.
Once you understand the ins and outs of your boss, you can plan ahead for tantrums in the future. Come up with a strategy you can use whenever you're in a tense situation with him or her. This might involve focusing on something positive and ignoring the emotional turmoil or simply walking away altogether.
If your efforts to cope with your boss are failing, consider speaking to a live psychic about your concerns. Authentic psychic readings can give you insight into the direction of your career and let you know if it's time to start considering hunting for a new job.
