Caring for its employees’ health is a priority for this biotechnology firm. If they’re not feeling well, the medical clinic at headquarters can help by filling prescriptions, treating colds and running blood tests. If they need a pick-me-up, they can take any of 85 exercise classes offered weekly at the firm’s 24,000-square-foot fitness center. (Workers at other sites may access corporate gym discounts.) If their office chairs hurt, they can meet with consultants at three on-site ergonomic showrooms and select equipment that works better for them. Moms stay healthy by noshing on nutritious, low-cal meals at on-site cafeterias, taking stretch breaks with colleagues during meetings and dining on fruit deliveries from a local CSA. The firm’s Wellbeing@Work team offers workshops and classes on resilience and stress management.
