Pros: Its a job
Cons: Travel, low-wages, unpaid breaks, hard on the body, shift, never know when you'll be getting home
Management just doesn't care. They follow the minimum labour law regulations and aren't afraid to break them. Travel places frequently in a cramped vehicle that is generally poorly maintained - and only get paid after the first hour of travel (minimum wage to boot). They have no problems ripping you off whenever they can to make more profit so watch your pay stubs! They employ the oddest people, mostly because the job is so simple.
The job is not for the weak of heart - you will be up and down and sitting crunched up 95% of the time. If you're not small or elderly, up the ladder you go! Is it safe? Sure. Hurry up and count.
