There are monumental tasks to overcome from a MOL perspective. Firstly the huge hole in the deficit is one such task, not to mention unions.
Aer Lingus pumped €100 million as a one off into pension fund on floatation, now they back for more.
If pension fund wins the €300 million it wants then pretty much no need to worry about EI future as there isn't one because you can pretty much guarantee they will be back again.
EI owned only by its shareholders one of whom with 29% will be voting against this as may other holders as well if realising the voting away its cash.
In relation to Unions, the adding of costs as you describe, is supposedly protecting jobs if listening to the Union, but ensuring loads of additional costs are added in to make reinvesting harder.
