Stan, A twist on the job sharing is the variable hours option. UsAir cabin crew does this and many other airlines cabin crew unions are looking at this as a way to minimise furloughs or redundancies. This could easily be applied to any union group paid by the hour. Their system is such that one group can fly up to 95 hours hard time, one group 75 hours and one group 55 hours. You bid by seniority which group you wish to be placed in. For those close to retirement or for mothers with small children the low hours option is coveted and allows their junior colleagues to keep their jobs.
