Millennials have a reputation for job-hopping, and last year the median job duration for 20-24-year-olds was less than 16 months. To hook young hires for the long run, some companies are hosting mentorship “mixers,” relaxing dress codes, and asking younger employees to play a role in the hiring process. Some experts recommend openly talking to Millennial workers about the chances they will leave, and using a “tour of duty” structure in which employees and managers agree upon a specific amount of time the job will last.
