Pros
The only requirement for getting hired is a pulse and a clean drug test. This means if you are in transition, have just recently moved, or lost a job unexpectedly, you can work here for minimum wage to at least make something. It was a diverse place, I'll give it that. I haven't seen as many people with disabilities (including visual impairments), and trans* folks in the workplace in such force of numbers, ever. So, props to them for whatever outreach or accommodations they make. They do offer healthcare. It's not great, but they don't make it a hassle. And it's pricey.
Cons
You are a number and unless you manage to get hired as a trainer or management, you have no identity or incentive to contribute. You follow the script or procedure and take the lumps for missing one of a million little things. HR issues are difficult to resolve, but automated tracking will always catch your mistakes - meaning, the company is never wrong and you often are. You are fired after a certain number of infractions. Some infractions (clocking in late because your computer is frozen, for example - and good luck getting HR to reverse that) cost a quarter point, some cost up to 2 whole points. You have 8 points until your canned. Think a life meter like a video game. Resources are challenging to get. I had to bring my own pens and paper. As a trainer, I had to sneak into other departments to steal paper clips and markers for use in my department. I had a curriculum to copy and prepare and no official access to a copy machine. I literally had to hustle copies. I have to assume that there's some incentive for management not to spend money (maybe it comes out of their bonus?) and it keeps the actual implementation of work from having any quality or consistency. It's not unlike prison, and the breakroom feels like a prison yard. I saw management enforce rules unfairly and unequally, and target specific people (read: people of color) for their clothes and style in ways that I read as racist. In addition, I saw women being treated poorly as well. This is a job of last resort, so none of that surprises me, but steel your nerves for a really shitty environment.
