The company wants people to stop accruing leave entitlements by forcing us on LWOP. Don't do it and you run the risk of a CR notice landing in your inbox.
This isn't just targeted at the junior crew for what its worth. If the bottom 400 recently hired SO's all take LWOP (and you would be stupid not to take it), guess who they are coming after next.
Its a threat to everyone. Want a future at Qantas? You have 4 weeks to take LWOP.
