Pros

Annual bonuses You get to work alone in your vehicle

Cons

Bad supervisors Pay is no good Benefits cost too much with what you get paid Union dues are getting higher and higher and they don't even help you get a decent raise at all yet they brought up their dues to $77 from $20 and only gave the drivers a $1.50 raise 😡 Company have become extremely strict with everything No room for growth Pay is not worth it to drive to New York City from New Jersey.

Pros

The hours were consistent at least

Cons

Poor management, staff is incredibly cliquey, new hires will be bullied by current staff, no one truly has your back. There is NO HR DEPARTMENT and if any of the staff caught wind you tried to file a complaint, you would be bullied for it. So, if you have a work complaint suck it up.
