Yeah, I'm confused by this one, as salaried employeees. Unless your salaried job is making you clock in, why not work the 3-4 hours it takes to do your normal job, take whatever meetings, and go do literally anything else with the rest of your now paid-for free time?
I mean, I don't subscribe to the mentality (I usually have side projects for my work that have tangibly lead to promotions in the past), but if I were, I'd just use it for more free time.
