Yup, way to go! Scrap seniority and replace it with a loyalty system!
Every year with the company, get a pay increment as reward for loyalty, as a loyal employee get enhanced rights to bid for work as your loyalty, measured in years, becomes greater than those with fewer loyalty years.
Have fair leave system based on points for more/less attractive leave periods.
Spread standby equally throughout the workforce.
Most loyal pilot gets first choice of chicken!
