How the pandemic paved the way for more flexible benefits in 2021

December 21, 2020

Burton Goldfield, president and CEO of TriNet, a professional employer organization (PEO) that provides comprehensive HR services to over 16,000 small- and medium-sized businesses, observes that there’s even less use of other standard benefits. “With remote working prevalent across the country,” says Goldfield, “there has been a significant decline in the use of commuter benefits,” such as paid transit cards or mileage reimbursement, as well as lower usage of healthcare and dependent care flexible spending accounts. “Of particular note is the decrease in preventive screenings, due to employees canceling or delaying these services as a result of stay-at-home orders,” he adds.
