Without a doubt, the biggest workplace changes involve computers and communication. Employees are linked to their jobs practically around the clock. There's been a revolution in smart phones like the Treo and BlackBerry that allow people to communicate by E-mail and IM (which your kids will soon explain, if you don't understand) and access the Web from soccer fields and doctors' waiting rooms. If you haven't used them yet, you've almost certainly been to a dinner party or school event where someone's hunched over in the "BlackBerry prayer," thumbing an E-mail response.
