In my (thankfully small set-size) experience even with attitude problems it's not easy to fire people. It's really seldom that you have to fire someone who is just a right asshole with no redeeming qualities - quite often they are toxic because they have some mental health issues, or have really bad social skills, or are just for one reason or another really frustrated and taking it out in the wrong way (none of these are excuses to keep them employed mind you). You can be relieved after the fact that they are gone while still not enjoying having to actually fire them.
