No, I literally meant that. It's an alternative to not working at all.
if we assume that this is the middle of the day, so i work 2 hours normally, then 4 hours with 45 minute breaks and then another 2 hours normally, i might as well just work 2.5hours normally, take a 3 hour break and then work another 2.5 hours normally.
so no, really, i don't see any benefit in that arrangement.
