Well, this is certainly interesting. Canadian unions are now asking for additional pay for employees with company-provided BlackBerrys, due to what boils down to 24/7 availability. We already knew that BlackBerry overuse has increased the average hours worked per week from 47 hours to 71, so the request certainly carries some merit. The Canadian government has said it’s willing to talk about the issue, but Carleton University professor Linda Duxbury warns that people might get more than they bargained for. If companies are paying for the BlackBerry use, she argues, they might send more off-the-clock or after-hours emails or work orders, resulting in even more hours worked per week. It’s a complex issue, and one worth keeping an eye on.
