100% of crappy owner is on Kraft. EJM as a management company will make recommendations. They will employ the flight crew/mechanics, perform H.R services and payroll. Schedule maintence and any compliance or correspondence with taxes or FAA, but the nuts and bolts of how the flight department is run comes down to the owner.
At least a couple years ago he was only employing three pilots per airplane, which for a global operation with high flight time is woefully understaffed. I know for a fact that pay was nothing more then average which also lead to a revolving door. Who wants to work for average pay when your flying more then average, on weekends on holidays etc. Too many other jobs out there flying the same jet that pay "average" or more yet have a ridicously better quality of life.
When you hear a pilot "only" works two weeks a month, especially a corporate pilot, you have to remember it's more likely then not that person is away from home half the year. If you fly internationally, not only are you always away from home but your potentially 12 time zones away from everything and everyone you love. Don't get me wrong, being a pilot can be the greatest job in the world, but even Paris gets old for the 100th time while you are missing Christmas for the second year in a row or your kids birthday because you have an inconsiderate "owner".
