Don am in total agreement.
QH SH pilots lose money and so do JQ if they don't extend.With MBT for many patterns, gaining adequate rest is nigh on impossible, the threat is always there that next day pay will be lost... ..How the 'regulator' ever allowed loss of income to be ignored considering the subtlety applied by management was a disgrace.
If one considers the potential PERSONAL liability from operating outside the rules ie CAO 48 in its various guises, any extension place the onus fairly at the pilot's feet.
Just say no. Or simply ask the company for an indemnity in writing from any resulting incident or accident. As happened with me a long time ago, they will never give you one! So without I would never extend.
Roster construction is an issue that needs urgent addressing, which CAO 48.1 was to address, but given the can kick by the 'regulator' it is pretty easy on whose side they fall...
