My friend, Bob, saw a particularly stellar case of PD play out over the last year at his place of employment that culminated on Monday.
Bob works in a department that does programming and websites. Bob worked with a guy, Jim, at a previous place of employment, and when Jim applied to work at Bob's new department, Bob was hesitant. See, the job required skills that Jim did not exactly have, but were similar enough that with study, Jim could probably learn fairly quickly. So, based on the fact that Jim was fairly likable, and with the stipulation that Jim take training and get up the speed, the company hired Jim.
In the past year Jim has:
1. Shown NO initiative to learn what he needs to learn.
2. Training has failed.
3. Extended his lunch hours to 2 hours from the normal 1 hour on a regular basis.
4. Been using his personal computer on the companies guest network, which IS allowable, however, he has used this access to:
a. Spend the hours after his 2 hour lunch playing MMORPGs
b. Spend hours reading gaming and other more "Adult" forums
6. Basically not produced much of anything useable for most of the time he's been there.
When it was realized that Jim was taking two hour lunches, and got caught playing games (by a coworker who happened to walk by and see it before Jim closed the laptop), logging was turned on for the guest network.
After a week, the company had more than enough evidence to fire him. He was working maybe about an hour a day, and the rest of the time was spent on various forums and online gaming. He was escorted out Monday, and when they cleaned up his computer, they found all sort of fun stuff, including evidence that he knew he was going to be fired, and was collecting info to start a legal dispute against the company for said firing that hadn't yet occurred.
Bob seems pretty sure that Jim's lawsuit isn't going to happen...
