Employers which are concerned about retention know that retention and job satisfaction go hand-in-hand. So a recent study about the job satisfaction reported by Millennials should give all employers some pause.

According to the Emerging Workforce Study conducted by staffing firm Spherion, only 34 percent of 18 to 24 year olds rate their current level of job satisfaction as very good or better. That's the lowest job satisfaction rate in among all age groups in the American workforce.

The low job satisfaction rates are very troubling as they lead to job hopping and that leads to lower productivity for employers, higher prices for consumers, and perhaps even less solid open ice checks in the NHL. Well, perhaps not that last issue, but that still should be a concern to us all.

Forty-eight percent of these Millennials indicated that they were likely to leave their employers within the next 12 months. And they don't see this job hopping as a negative. Some 61 percent said that they have increased their career potential by periodically changing jobs. Even though they're at the beginning of their careers, already 56 percent are employed in a field different from that in which they were employed when they first entered the workforce.
