Something feels a little off in this particular case. I feel like there is an implied increase in flexibility with WFH for many of us here, but I doubt call center employees get that benefit at all.
They likely get some of that. For example, I do laundry, and for me, 70% of that is popping one load in the washer, transferring to the dryer and back out. After that, I quickly fold and put away. That sort of task could easily be done I suspect while on the phone with a wireless headset. There are probably other household tasks that don't take much brainpower that could be multitasked.
