      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.
