Pros
Holiday pot lucks (with meat provided by RDI)
Will pay for exercise/gym as long as you're willing to meet the requirements (otherwise you pay).
Ok benefits
Some projects offer remote work after probationary period, including equipment
Sales jobs may pay higher than customer service and tech support
Everyone is super nice to you in orientation+training (it doesn't last)
Kontras
No attention to dietary restrictions for pot luck, causing some people to not be able to enjoy. Definite focus on unhealthy eating with most snacks, meals and beverages in the canteen being crap, and a culture that seems focused on being unhealthy, and enabling obesity.
False sense of culture presented during training - real culture becomes obvious after. Claims of "family" style, interest in feedback, inclusiveness and so on largely false.
Climate controlled by site director, and they're generally interested in minimizing the cost so you may be too hot/cold.
Deceptive culture, two sets of rules - one for the clique of managers, supervisors (glorified team leads) and 'special' employees, the other for everyone else. I.E. Favoritism. You can feel it from the moment you get out of training.
Lack of interest in actual feedback, coupled with defensiveness or attacks
Dishonesty and some bullying by leadership
Very strict rules about bathroom use time (20 min/day). If you have a medical excuse, you can get an exemption so you aren't written up, but you won't be paid for that time in excess of 20 min/day.
You're given your supervisor and manager's phone numbers to contact outside of work but good luck getting a response every time you need to contact them!
Pathetic training by people with no experience in that area, who are led by onsite directors with no experience in education, either, leaving you potentially ill-prepared for your job.
Sub-par salaries, which they blame on the clients.
Holidays and holiday pay depend on both RDI rules and client rules, not just RDI, so you may not get vacation pay for some holidays.
Very stingy company shoveling money upwards to the C-suite while maybe people in lower positions get crap pay, and some of the people you promote end up giving too much of their personal time to you without proper compensation.
I could go on and on....
