Their "cost-base" problems stem from them buying large amounts of fuel at a high price. The price then dropped. While the airline (like the rest) charges its customers fuel charges it is still having to absorb the cost of using fuel that is priced higher than its main competitors.
That's before even considering the pension black hole....(like everyone elses pension black hole.....the public service one is over 1 pounds so far).
Different terms and conditions for new employees is nothing new either, most employers do that.
The union role is not so different either. They ask their menbers (they have to by law) if they want the ability to strike and get a reply....over 90% did. The COURTS held that they should not have included those that had accepted redundancy (the law does not mention that...)....the union is mulling an appeal (which will probably succeed...the redundant members were still members.....they could action the union if they were excluded)
