When employees are working at an office, it can be easier to spot someone who may be thinking of quitting. Phone calls taken outside, extra time-off requests, and a detached attitude could be indicators they’re interviewing elsewhere. When everyone is remote, however, it can be harder to spot.

“The key warnings signs . . . are often related to whether that employee is engaging in what we call withdrawal behaviors,” says Angela Hall, associate professor in Michigan State University’s School of Human Resources and Labor Relations. “Withdrawal can take two forms: physical or psychological.”

Fortunately, research from meQuilibrium, an employee resilience solution, found that most employees—60%—have no intention of quitting. “But 7% are perilously close to jumping ship,” says Andrew Shatté, chief knowledge officer and co-founder of meQuilibrium.
