The benefits are great at the USPS. However, salaries aren't great. It's difficult to witness much of the waste of deadbeat full-timers and even some incompetent staffed contractors. Outsourcing to Accenture and IBM are often just massive give-aways with no-bid contracts. It's a demoralizing environment along with finicial state of the Postal Service.
Managers have the same benefits. Plus, they get to telecommute 2-3 days a week! Since that benefit was given a year or so ago many of the managers have become even more disconnected with their job.
Managers also get bonuses which they deny. The bonuses are called "pay for performance". That's a joke because the metrics used for the PFP bonuses are ridiculous and encourage micromanaging which creates resentment towards supervisors. The entire workforce is demoralized. For most, it's difficult to leave the benefits.
