Generation gaps are nothing new. Imperfect communication between age groups plagued the ancient Greeks and current works alike.
Many an older worker chafes at an under-30 colleague who surfs the Internet, listens to his Sony Walkman and chats on the phone or with his desk mate, all while working on a project due in an hour.
Sometimes, of course, he isn’t corking, and that’s a whole different issue. But sometimes he is getting lots of great stuff done. In the meantime, the different work styles create a case of "Would you please shut up" vs. "Lighten up. Get a life"
Marc Prensky, vice president of Bankers Trust and founder of its interactive learning subsidiary, Corporate Gameware, was on point in Across the board, a publication of the conference board. The business research organization titled Prensky’s article "Twitch Speed," a reference to the fast pace of video game play.
Today under-30 workers likely grew up in a multimedia, technology-rich, twitch-speed environment. Prensky says they simultaneously did homework, watched TV and listened to music; this exposure changed the ways they receive and process information.
Baby boomers and older workers may or may not have done homework by TV, but much else has changed. Sociologists say the over-30s are more likely to want room doors close. TV off, one thing happening at a time, quiet, please!
When the two heritages clash in the workplace, it pits comfort with speed and "multitasking" against comfort with deliberation and focused concentration.
Sound familiar If the gap has become a chasm in your workplace, it’s time to talk. Both work styles can be productive, but both sides need to make accommodations so the other’s productivity isn’t impaired.
