Employees quit their job for many reasons: Either the boss is a pain in the ass (most cited reason), they got a promotion somewhere, they choose to go back to school, etc. 

But when employees do leave, productivity sinks, morale tanks and the remaining employees have more work until you find a replacement. Plus, on-boarding and training is an expensive affair. 

Losing a single employee can cost your company tens and thousands of dollars. So, it makes sense to identify the reasons why your employees are leaving you and what you can do about it.
