Well, I can say as someone who supports flexible scheduling and has run a team that way it's not so much that I ignored or didn't think about jobs where it didn't work so much as different jobs have different requirements. I ran a team of software developers, system administrators, and a help desk. The software devs had near complete freedom of scheduling, the sysadmins had a little less, and the help desk had almost none since they needed to be there when the people they were helping were. Everyone had as much flexibility as their job allowed and it worked great. It sucked that the help desk didn't have the flexibility, but they understood why, and I tried to find ways to provide other perks. Plus on the flip side they'd never find themselves trying to resolve an outage at 1 in the morning on a Sunday.
