For a lot of folks it's a time optimization problem. You have to spend X time getting ready and commuting to work that in most cases is unpaid. If that takes you an hour and a half all in (half an hour each way and half an hour getting ready) that's 1.5 hours a day or 7.5 hours a week. Nearly a full extra "work day" a week that you're uncompensated for.
At the high end of things you have folks in medical professions who not uncommonly work shifts like three 12 hour days and get paid as if they worked 40 hours.
At the low end you have things like hourly workers being forced into doing split shifts where they'll be asked to cover rush hours at a coffee shop or something (7-9am) and (11am - 1pm).
