I'd call you a cynic, if I didn't agree with you so much. I've got 34 paydays left until I retire (but whose counting). And then I'm out of there on the Friday before my 62nd birthday. And I don't trust anyone who works in HR anywhere.
Like I say, I don't trust any of them. And I work for a GOOD company. They keep you around as long as they need you, then sayonara, baby.
Fortunately, they have me stacked up with 5 years worth of projects, so I think I'll make it before they're "done with me". I hope.
In my Dad's case, he was cut by his firm six months short of qualifying for a pension, which in that era was ten years. My Dad had worked for that firm for nine years and six months. That blow badly damaged my Dad's self-esteem and caused my family great hardship. But hey, who cares? That's the workplace, they get you one at a time. That, my friends, is one reason why I'm a cynic about the workplace. (The other reason was my former venue of employment from which I retired, but we won't go there. It's past history.)
