To avoid high turnover, Mary Chocolate Co. holds a "top seminar" for university students every year as a means of retaining them once they are hired.

What is so extraordinary about it is that preparing the seminar is part of a training course for the previous year's recruits and marks an important event for them.

The new employees, fresh from their final year in college and on the payroll for only a few days, work out plans, including preparation for distributing materials to the next year's recruiting targets.
