Keep in mind that no CP,honestly, will support crew retrenchment because it negatively effects safety. Look back in history and you will inevitably find financial departments responsible for retrenchments. In my humble opinion, no financial department should be involved in operational decisions. Wishful thinking, I know
In my limited experience you cannot reduce aviation direct operating expenses, long term, by cutting crew. You cover direct operating cost by increasing revenue, which means more flying. In the long run more flying results in needing more crew, therefore cutting crew is counter productive.
I may be wrong
