Half the woes stem from the fact that the AIMS in GF does not have the modules for bidding and for equalisation - those were deemed expensive dispensibles when the last management (under H.A.) bought the system. Since then, no one wants to get the modules as they are an additional expense. Besides, there is a lot of controversy, with Sabre trying to push the sale of its own system, etc.
If the blocks are tough - it is a reflection of the pressure on the rostering lot to make the maximum utilization. The rostering staff has no choice but to oblige the top management, and the Managers are too busy flying the line, or on leave or attending to dubious obligations (like helping their buddies or countrymen become instructors), or ferrying planes (that any line pilot can do and ought to do) to bother about what is happening on the line, and make a call for better conditions.
Wait and watch - the situation will worsen with the arrival of the A319s, and the possible departure of some Omanis (If Sal-e's prediction takes shape).
