Answer: Job Content
The majority of people leave their jobs because the tasks they perform at their jobs are not what they thought they were going to do when they were hired. Either the employee did not fully understand the expectations of the role, or the position did not develop over time in the career opportunity they had expected.
According to Recruiting Times, it costs $7,000 to replace a salaried employee, $10,000 to replace a mid-level manager, and $40,000 to replace a senior executive. Add the cost of lost productivity or lost opportunity, and the amount could escalate to 1.5 times salary.
At this price, wouldn’t it make sense to make sure new hires fully understand what is expected in their role? Just because they “can” do the job, doesn’t mean they “will.”
