When you’ve got a bad boss, you know it. A truly terrible manager has the power to decimate your enjoyment at work, but even slightly rubbish bosses can have a detrimental impact… even if that’s just increased eye rolls and grumbling.

We tend to think of each of our bad bosses as uniquely bad in their terribleness, but the reality is that bad bosses tend to fall neatly into certain types. And the good news is that by learning about these types and how to handle them, we can all be better equipped to deal with a rubbish manager. This is what Debra Corey, an award-winning HR expert, explores in her new book, Bad Bosses Ruin Lives: The Building Blocks For Being A Great Boss.

“I genuinely believe that the majority of us want to be a great boss,” Corey tells Stylist. “We want to wake up in the morning excited to come in to lead and inspire our people, and leave at the end of the day knowing that we’ve done something to help them be their best and enrich their lives. But too often this isn’t happening, with well-intentioned bosses getting it wrong. Instead of being the great boss they want and need to be, they’re doing the opposite of what they set out to do – they’re making bad decisions, taking bad actions and having a bad impact.

“According to our recent global study, 99.6% of people have had a bad boss and 80% of people admit to having been a bad boss. What can we do about that? How do you spot the traits of a bad boss so that you can actively and intentionally do something about them?”

The first step in dealing with a bad boss is identifying them. Knowledge is power, after all. So with that in mind, let’s break down the 10 types of bad boss Corey explores in her book, and how to spot the warning signs that this might be the type of leader you’re up against.
