Pros
It's a straightforward job that's easy to learn. If you plan to have a side gig, this is a good one to pick up in addition to your main income. If you like the industry and want to move up quick, this is also great for you. If you enjoy working with people or you would prefer to work alone, there are options for both as long as your willing to speak with the site managers and supervisors about your preferences. They will actually take the time to listen and adjust accordingly!
Cons
The hardest part is the overnight timeframe. If you're not already used to that shift, it can be a tough adjustment. There are part time hours available however, which makes it easier if you have other work you do as well. You'll also be working around some cleaning chemicals; you are protected of course, but the smell may bother some more than others.
