I had a problem of burnout in the past. My boss was an asshole, he lacked any planning or technical skills, he want impose his point of view without listen anyone opinions. He change assigned priority every seconds and want to take technical decisions without any knowledge. He was crusty when someone try to reply to him and explain a different point of view. He changed position during the time trying to earn merits and charge others to his own faults. He ever defend one of two employees who he like, even if they are completely wrong. Also holiday planning was a nightmare: he pretend to stay one month in holiday and we have to cover this period (I come from Italy where everyone usually go in holiday in August). Unfortunately he was one of the founder and of the owner of the company. When he decided to sell his share, we opened a big bottle of champagne. Now, with a democratic, polite boss (that is also a technical guru) the climate in the office is great and no one want to leave.
