Company bottom line: although most businesses don’t track this cost, studies show that replacing an employee that was performing to a good standard can cost the business 150% of their salary to replace.
Knowledge base in the company: employees who leave a company, particularly after a prolonged period of time take institutional knowledge with them. This will make your business, at least temporarily, less efficient. Research by HR Daily Advisor showed 42% of the skills to correctly perform a role are only known to the person in that role.
Performance and moral: if many colleagues are leaving, remaining employees may begin to feel more insecure and less motivated. Performance levels are likely to be impacted by former employees leaving and new employee onboarding.
However, further studies indicate if millennials are engaged at work, 64% are unlikely to switch roles in the next year, even if the job market improves in their area. So, key to employee retention is building and maintaining engagement as early as possible.
