Tennis elbow, tendonitis, sore and strained muscles. These injuries aren't always sports related. According to the New York Times, an increasing number of bartenders are being sidelined by pains and sprains because of their behind-the-bar athletics. Bartending has never been an easy job. You're on your feet a lot - but these days new drink trends are making it even worse. Now the run-of-the-mill drinks, like a cosmo or a martini, don't cut it. It's all about the ultra fancy craft cocktails. These are drinks that require serious stirring, at least 60 revolutions per drink. Or intense shaking to make sure it's properly chilled. New drinks even require special larger ice cubes, which chill drinks faster and dilutes them less, but it makes a cocktail shaker much heavier. Lisa Raymond-Tolan is an occupational therapist based in New York City. She says when bartenders shake those heavy mixers they're wreaking havoc on their shoulders, wrists and hands. It's especially bad when they're showboating and doing a drink in each hand. Bartenders are bending and lifting and torquing their body for an entire 8 to 12 hour shift. They're constantly jarring their wrists, hands and elbows when they smack a shaker to break the suction. One bartender mentioned in the article shook his cocktails so vigorously that he ripped out a set of screws that had been inserted in his clavicle after a snowboarding accident. He was off the job for weeks. The problem is so bad that some bars have several bartenders a night who are on the injured list. So, bar owners are taking action. An owner in Los Angeles is hiring physical therapists from the sports world to work with his staff on safe mixing techniques. Other bars are holding training sessions for bartenders. That being said, there is one thing most bar owners AREN'T doing for their workers' health, and that's offering them health insurance.
