You can’t pay people enough to do some jobs.
It’s not money that drives people away. One recent study showed the average salary differential for job hoppers was a little more than five percent. People don’t leave their jobs for money.
Companies with low turnover typically have good managers, and those managers provide employees with challenges, opportunities, and confirmation that they make a difference, supported by recognition and awards.
Provide those, and turnover will fall faster than a pair of cheap socks.
