In defense of the person you're replying to, a lot of large corporations have "employee improvement plans" that are designed specifically to create documentation that can justify a firing, especially when that firing is for some other reason (e.g. "not getting along"). The improvement plans have nothing to do with getting the employee back on track, but rather to either 1) show that the employee is unable to keep up with artificially high work demands, or 2) get the employee frustrated enough to quit.

That means that when a person is fired, the stated reason for that firing is not always the same as the real reason.
