A third-world Marxist dictator confiscated Delta's bank account.

That is pretty much the textbook definition of a "loss due to an extra-ordinary event".

Management told ALPA to stick our contract language where the sun don't shine and called that event an "ordinary expense".

ALPA would have won that grievance easily. Management pulled that accounting trick for the sole purpose of screwing the pilots out of some money. The same reason they gave all the non-contract employees raises in December 2015 instead of the traditional January 1st.

I would like to know the effect of dropping that grievance. In the future there will certainly be other accounting charges that all other corporations have traditionally recognized as non-recurring, one time or extra-ordinary. Is management now free to deduct all of those from the pilot's profit sharing?
If so, I'd call that a change to our profit sharing program.
