Debbie Cohen and Kate Roeske-Zummer, cofounders of HumanityWorks, are sounding an alarm bell for employee retention. Record numbers of people are quitting their jobs due to burnout and better opportunities. Those resignations leave their former colleagues burdened with even more work and a sense of despair. Cohen and Roeske-Zummer argue that employers should re-recruit their existing employees and even think of them as customers.

Cohen and Roeske-Zummer wrote the HBR.org article "With So Many People Quitting, Don’t Overlook Those Who Stay.”
