We have something called the 10 and Two Program, where consultants can work 10 months out of the year and take two months off. About 20% to 25% of our consulting staff takes advantage of that program.

As a small firm, we'll get together with you and try to create a customized working model. Some people do a part-time model, and others do a no-travel model. We have something called a 50-50 model, where consultants do 50% firm work and 50% client work.
