Inc. – When employees start leaving in droves, the first step is to find out why. Conducting exit surveys is the simplest way to see what departing employees have in common. Gerrit Brouwer, CEO and co-founder of the onboarding app Appical, said collecting exit feedback is an untapped source of information leaders need. Take the time to dig into feedback from employees who are leaving. Let them know you want to make the workplace better and would like any thoughts they have on improvements. Then, compare notes from other exit interviews to see what trends need to be addressed immediately in order to halt turnover.
