Comment Another factor, worldwide workforce (Score 1) 18
I think another contributing factor, specific to business that provides 24/7 support, is that it's now easier than ever to have call centers in multiple countries, everyone working "normal" business hours, but still making good on their 24/7 coverage. Of course, a lot of those call centers are now exclusively in places like India, so the 24 hour shift work has just been outsourced, too.
