It’s still early to say how the post-pandemic work environment will look. Only about 28% of U.S. office workers are back at their buildings, according to an index of 10 metro areas compiled by security company Kastle Systems. Many employers are still being lenient with policies as the virus lingers, vaccinations continue to roll out and childcare situations remain erratic. But as office returns accelerate, some employees may want different options. A May survey of 1,000 U.S. adults showed that 39% would consider quitting if their employers weren’t flexible about remote work. The generational difference is clear: Among millennials and Gen Z, that figure was 49%, according to the poll by Morning Consult on behalf of Bloomberg News. “High-five to them,” said Sara Sutton, the CEO of FlexJobs, a job-service platform focused on flexible employment. “Remote work and hybrid are here to stay.”
