With news that a 55 year old BA hostess has asked for her job back. It may be close to a "test case" since a goodly number of employers are entering into the spirit of the proposal - before it becomes law.
It is hoped that BA will see the writing on the wall. Thus giving experienced staff more time at work if they want it.
It is already thought that they will be hard pressed to produce a case against the EU directive when it comes into force. In fact, they just might not have a choice.
