Why have you quit a job in the past? Chances are pretty good it’s because you hated your boss. We polled Workopolis users and this was by far the number one reason people say sayonara to a job.

Here are five of the top reasons.

You hate the boss: This is hands down the most common reason to leave a job. The boss was a tyrant, the boss was crazy, the boss was incompetent. We asked and got stories of rude, disrespectful, and even drug addicted bosses. People can put up with a lot but it is very difficult to deal with someone who is horrible on a day to day basis. A boss who loses employees would do well to take a good, hard look at his or her own behavior.

You’re bored or unhappy with the work: We’re an entitled culture and we all think we should love what we do and do what we love. That’s the message we’re bombarded with by the media and those people who post inspirational quotes on Twitter. “Do what you love. The money will follow,” and whatnot. The trouble is that a lot of work is mundane and boring and people aren’t going to love doing it. Also, what some people love is lying on the couch watching TV. Then there are times when you’re stuck in the wrong position. You’re not challenged and you become increasingly unhappy, but they won’t or can’t move you for whatever reason. That’s when people walk.

The culture isn’t a good fit: You don’t get along with the boss. You don’t get along with co-workers. People are just pains, aren’t they? But often there’s underlying turmoil in the workplace that higher ups might miss, like a culture of bullying or an exclusionary social hierarchy. One person might be creating a toxic environment, or it could be a bigger problem.

A better opportunity: They can’t expect you to stay forever if they can’t offer the better opportunity themselves. These days, people also seek out new opportunities regularly, as jobhopping has become the norm, particularly among millennials, who stay in jobs for less than three years on average, according to Forbes. This is partly because they’re always dissatisfied (see reason #2), partly because they are seeking new experiences and additions to their skill set, and partly because they have no loyalty. It’s also because careers aren’t seen as following the same trajectory they once did – you can no longer start in the mailroom and work your way up to CEO – and because companies themselves have no loyalty. They will axe you and/or your entire department without notice or a backwards glance and nobody wants to wait around for that. Which brings us to…

You think you’re about to lose your job: If you feel that the corporate environment is unstable, you might, wisely, run before the ground opens up and swallows everyone. Also, you can often tell when you’re going to get fired and, when you start to feel the wind turning against you, the wisest thing to do, usually, is jump ship rather than wait around for the axe to fall.

We asked some people why they had quit jobs in the past and here are some of their answers:

    “Because my boss was a pathological liar and a drunk.”

    “I was actually allergic to it. I worked at a sorting station for a clothing donation company. I was on the sorting line, trucks would come in and 2 guys on the truck would cut open the bags and send them down the conveyor belt for us to sort through it. Sometimes though, there would be garbage and dirty diapers in the bags. It was NOT glamorous. I was 16 and my boyfriend worked there and I felt it was for a good cause. … the dust+ in the place sent me into asthmatic fits and my eyes swelled up so I had to quit.”

    “The store hired this awful manager, just awful. But she was a good talker and she was a single mom with kids and was very attractive. She started stealing from the store we worked at and was telling the owner that it was me. Though I had been there a while he took her word for it. Before he had the chance to fire me I quit. A year later he found out she was stealing and apologized.”

    “Because I was micromanaged and treated with disrespect by a dinky boss who thought he was a lot better than me because he was a “manager.’”

    “To seek fame and fortune about three years too early for the thing I wanted to do. I am prescient that way, just not smartly prescient.”

    “Because they wouldn’t pay me what my job was worth in the market.”

    “Manic-depressive, coke-sniffing boss who would call us names while we worked crazy unpaid overtime and the next moment would be hugging us, crying. We all walked out together in the middle of a huge project!”

    “The boss yelled at me in front of everyone. So I calmly and thoroughly told her off in front of everyone, took my coat and purse, and strolled out.”

    “For a better job”

    “Because my boss got fired, I walked out right after him.”

    “Soul sucking work. And they let me work 4 day weeks (at a 20% pay cut) for a year, then took it away because it “looked bad” that some people were getting “special privileges.” Note that I was able to get all the work done in the 4 day week.”

    “My manager told me the internet was just a fad.”

    “It was sucking my soul and faith in humanity away. I started to hate coming into work.”

    “I was bored and needed a chance. I quit my jobs about every 5 years.”
