True, there will always be people who leave no matter what bond they have, but it certainly is a huge deterrent. No idea what the details are of the new scheme, but it may not even be a decreasing bond!
RYR just need to open their eyes, rather than firing more money at people, just listen to what the current workforce want.
A Transparent base transfer system and an annual leave system that works and a bit of respect. They wouldn't have problems retaining people, I certainly wouldn't have left.
