The more robotic the work, the greater the benefits, we think. More research needs to be done on creative work and teamwork, but the evidence still suggests that with most jobs, a good rule of thumb is to let employees have one to two days a week at home. It’s hugely beneficial to their well-being, helps you attract talent, and lowers attrition. JetBlue allows folks to work as far as three hours from headquarters—close enough to come in now and again but a much bigger radius from which it can draw applicants. When I asked the people at JetBlue about this policy, they said it helped them gain access to educated, high-ability mothers who wanted flexibility in their jobs. The airline believes this policy has improved the quality of its workforce.
