Pros
PACCAR is a stable company...decent benefits and retirement plans. Lots of opportunities to move into several divisions and develop a pretty decent work history that can be as diverse or specialized as you want it to be.
Cons
Salaries are below average for industry if you aren't a manager. But to earn the big bucks, you will have to jump through a lot of hoops and follow some Draconian rules. Big idea thinking or outside the box thinking is not really encouraged or if an idea is voiced, you need to be wary of opportunistic co-workers who will try and take credit for it. And once you reach a certain age, you will be stuck with no way out other than being down-sized or if you get lucky, can retire. It's not experience they want, it's getting people at half the age and half the salary. They make no effort to allow these people to be trained and mistakes that could have been avoided occur.
