Our company offers free massages to employees. I don't work in that office, but I get at least one mass email per day telling me that there are open slots in the massage schedule. I once heard that when you get an email or an IM, it interrupts your work day you lose at least five minutes before returning to your work at the same level before the interruption. If that's true, these mass emails are costing the company massive amounts of cash. Of course, if you did actually lose five minutes of productivity for each email or IM, you'd get exactly nothing done each day since email comes in on average one per minute. Really I'm just upset that I don't get the massages.
