this is a tough one. From what I know (and I'm not an expert), once you're over 65 you're not entitled to redundancy. There is very little legislation protecting workers over 65. Likewise, I think the agesim claim previously mentioned only applies to workers between 18-65.
The only POSSIBLE avenue I see for your firned is this -, if she is so inclined, she could hassle her employer a bit by demanding to see their employment contract - every worker is entitled to an employment contract within 3 months of joining a company. In all likelihood the employer will not be able to produce one on the spot (without legging it off and typing one up that is), at which point she could claim that the employer changed the terms of her employment ad lib. Maybe then she could have a valid claim for some small compensation, or at least get a few weeks pay off them. Sorry I cant come up with anything better.
