Pros
Decent coworkers. Kind of like the camaraderie you feel with fellow hostages or the occupants of a sinking ship -- you don't know each other too well, but you're all in it together.
Upward mobility. Easy to move up in the company if you're willing to work a lot more for the same amount of money.
Cons
They don't know how to treat their employees. Everyone is laughably underpaid, but expected to work longer hours and be more productive than other employees making the same salary. Writers are driven to near insanity, churning out content that it often rejected by clients. I've seen writers have breakdowns.
Vacation hours accrue at a minuscule rate. If you save up all year to have the maximum number of days available in January or February, so that you can take more than one or two vacation days, your boss will suddenly be unable to approve your leave.
They have no concept of work/life balance, and burden everyone with workloads that mean you must take your work home and work through weekends. You will never be paid overtime or offered any compensation for working past closing time.
I wouldn't recommend this job to anyone but my worst enemy. It's a test of mental strength working here. Anyone who can get past a year is amazing. But people who stick it out past that strike me as odd -- after a year of working like a beaver you could definitely find a position with better pay and much better benefits. So why are you still stuck at CL in an entry level position?
