Pros
Once upon a time Sourcebooks had a dismal 2 star review on Glassdoor. Notice how the last few dozen reviews are all positive with not a single negative critique? Does that seem suspicious to anyone? It's obvious and frankly pretty sad that the company forced people who still work there to write fake reviews just to get the ratings up. Don't believe a single one of them. The best (and only good part) about working at Sourcebooks is some of the co-workers. Aside from upper management, the people who work at Sourcebooks are hardworking and kind people and you will make friends with people there (especially when you are crying over some heinous thing your boss said to you or how many hours of work you are going to have to do into the wee hours of the morning).
Cons
Co-workers are underpaid, mistreated, and receiving the bare minimum when it comes to benefits. The worst part is the company will brainwash you with this "we're all a family" culture to make you think you are part of this special club when they are only saying those things to make you feel guilty as hell when you quit. They don't care about you and if they did they would pay you more, promote you, and treat you the way you deserve to be treated. Instead they go on and on about growth mindset and pressure you to work harder for the sake of the company. Why should you care about the company if you are not reaping any rewards? The very least they could offer you is a non-toxic workplace, but no such luck. There's a clique culture so that when you are in you are in, when you are out, you are very out and made to feel like an outsider. Co-workers are pitted against each other to create a competitive environment that makes you constantly feel on edge and isolated. If you had any friends at the company to begin with, you will lose them because of the things the company makes you do to succeed. The minute you achieve something in the workplace you are only rewarded with more work.
