Pros
Trucks are top quality. Benefits such as pension and 401k are excellent over the long run. There are many opportunities for advancement if you work hard, are a white male and your personality is a fit for the PACCAR culture.
Cons
Relationships are more important than competence, results or creativity. Benefits for regular employees are being eroded over time. Management is arrogant and deluded about what it's really like to work here. Smart employees have options and they are bailing on the company -- leaving behind a team of inexperienced managers who are leading inexperienced employees who generally lack creativity. Salaries are no longer competitive. The management team is almost entirely white, male, conservative and clean-shaven -- all others will feel uncomfortable and will have to walk on water to get promoted.
