This article is a few years old but, as the saying goes, “an oldie but goodie”. The trend toward bringing health and wellness services directly to the workplace is picking up. This piece of research, even with its methodological limitations (single employer site, no control group), is still a breakthrough piece of research in backing up with data what employers have discovered: On site care has some very measurable benefits, in outcomes such as decreased sick days and absenteeism. But even if your employer does not provide those services, remember to provide those services to yourself.
