This is from a few years back but the best example of Professional Darwinism I've ever seen:
b/g: I used to work for a residential home for at risk children. We were broken up into different groups, by houses and each house, theoretically had three employees working as a team. To be offered employment with this group, you had to have certain qualifications (college degree for example), you had to pass an intense interview process and background screening, as well as attend a month's worth of training before being in the house. The people working on campus were relatively intelligent and generally had common sense and a great ability to think quickly on their feet. end b/g.
One woman on our campus started working in a house, after working as a supervisor for many years. (Essentially a demotion, but something she wanted to do.) As she was a supervisor, she should have known when paperwork was due, how to file it, and how to fill it out, as well as knowing the safety protocols on campus (such as off campus outings, transportation, and so on).
In her time as a house parent, she:
1: Drove over the lawn in a company van, because she didn't want to take the extra 20 seconds it took on the road. (With youth in the van.)
2. Left a pan of water of water on the stove, then left the house for 8 hours. When she returned home, she saw her error, picked up the pan, to take to the sink. but the bottom fell out of the pan and scorched the floor. (requiring a replacement of the whole kitchen floor.)
3. While picking up one of the youths at an off campus activity, when the youth reached for the door handle (on the van) she started to drive away. She did this multiple times.
4. When it came time to turn in paperwork, (like monthly progress reports) she'd be WEEKS late. This was time sensitive paperwork and she'd hold up essentially the whole process of releasing the paperwork by not turning it in.
Because all of the things she did involved witnesses, she received a "corrective action" each time she did something wrong. I don't recall what she did to finally be let go, but it wasn't pretty, as she didn't understand what she did wrong.
