The company said that part time and job share didn't save as much as one would think, although you save a salary, you still have all the recurrent training, sim traing, lcencing costs, medical costs, recency and currecy requirements to worry about.
Pure laziness and lack of political will.
Suggest individuals will pay for their recurrent sim through reduction in salary over 12 months. Recurrency, such as Line Checks, would cost very little. Medicals can easily be met by individuals. Licence renewal every 5 years.
Then see if they can come up with actual costs which would render the idea prohibitive....
What's the next excuse?
