Unfortunately, the last "Pro" above is also a Con, because it means that those who actually work hard get treated the same way as (but often worse than) the bare-minimum workers. This is especially prevalent of those bare-minimum workers are tenured employees, or men. As long as the work is getting done and no one is filing lawsuits – and of course they maintain some token female managers – they don't care about how many people have had to succumb to toxic working conditions. They fail to take their employees complaints seriously, so they have managers creating havoc and making decisions that are bad for the company and no one to hold them accountable. Promoting the underqualified seems to be a common theme for PSC, especially if they are men and/or brown-nosers. You will only get ahead in this company if you do as your told without question for over ten years, and then you might have a chance at growth. If you get promoted before then, you somehow managed to get along with your manager on a personal level (claiming to like the same sports team or hobby as your direct superior will get you farther than actually processing solid work).
TL;DR if you want a job with advancement opportunities and growth potential, respectful treatment of women, genuine environmentally conscious procedures, and challenges that support your career growth, PSC is NOT the place for you.
