Lifting, slipping, tripping and falling at work make the office a dangerous place if you’re prone to clumsiness. Muscle sprains, strains and tears accounted for 38 percent of injuries requiring time off from work in 2011, according to the Bureau of Labor Statistics. Back injuries from “lifting and lowering” were the most common, at 22 percent, followed by injuries from falls. “Stressed-out, overworked and overtired employees make workplace accidents and injuries more likely,” says Kevin Meyer, senior consultant at Hogan Assessments in Tulsa, Okla., which specializes in employee productivity. Experts recommend finding ways to relieve stress, such as meditation and exercise, and lifting with your legs — not your back — to reduce the risk of injuries.
