Justbelowcap,
my experience is, that the majority of problems with commuters lie usually with people, who commute say 3-6 hours DRIVING distance from the base. Often, they get attempted to drive just before duty, instead use the "B&B or Hotel" at the airport option.
People who commute from USA, Australia, etc to Europe can't afford to take the "last flight", therefore have contingencies in place and are usually well ahead their reporting time (24 hours, etc.) at base in a hotel, getting plenty of rest.
Just my 5 cents worth...
