All too often the benefits of such flexibility have flowed to employers.” In this case, “flexibility” means that you won’t be fired (in most cases) for answering a call from your spouse while you’re on the job, but you’re also expected to immediately answer an email from your boss at ten a.m. on a Saturday.
