Basically a pyramid scheme, they just have good lawyers.
Pros
You will meet a lot of people, the constant flow of employees coming and going will increase your network on LinkedIn.
Cons
A lot of reviews on here are from people who placed in temporary positions through RHI, not truly an employee in my opinion. The job they sell you on....Staffing Manager/Recruiter is not at all what it ends up being. It is a pure sales job. You end up working like a dog, 55+ hours every week, told people who take lunch will never succeed and no matter what you do it is never enough. RHI does so well financially because they find every reason they can to take commissions away from their own employees. Meanwhile, they tout they are the only staffing company not in debt, well their cheap ways show. The offices are the most sparse, stripped down space I have ever even seen. They love to hire young people who do not have very much experience because they can mold them and get them to think this is the way it is supposed to be. It's not. They use their employees for everything they have and toss them out with the trash. RHI likes to say they are in the "people business." Yes...they are in the business of using people. Their own staff and the temporary people they place at an 80% mark-up.
