The use of Facebook and “flashrobs” betrays the lie of the “digital divide”; several of my black co-workers have much more expensive gadgets than mine. Simply put, without basic English, math, etc. those devices don’t add any value to them as prospective employees. In fact, it has made them (and many non-blacks) even worse as employees - they don’t concentrate on work. I’ve seen toll collectors using them (while the line of cars barely moves), and there is no shortage of stories of BUS DRIVERS using them (which come to light when accident videos are reviewed).
Years ago I stopped paying attention in meetings where the boss couldn’t be bothered to call to task any of the people openly playing on phones during them (these aren’t long meetings, so even work-related emails can wait); I basically start jotting down things related to my own job that I have to address after the meeting. If it isn’t important enough to require full concentration, then stop inviting them (or me).
