She should see a lawyer asap. You aren't giving enough facts for anyone to analyze her case on the internet. You wouldn't ask a doctor for a diagnosis on DU. Many lawyers provide the first consultation free. Others will take cases on contingency after charging a relatively small up-front fee to consider whether they will take the case. Your friend should call around.
Your friend may have been laid off due to age discrimination. Age discrimination is very common and, unfortunately, also very hard to prove. That is because most people do not "hate" older people. And usually, employers do not let people know they are being laid off or fired because of their age. What is more, people do not realize that stereotyping older people as having bad memories, being unable to learn, being set in their ways, being grouchy, etc. is discrimination. And it is socially acceptable to devalue the traits that make older workers superior employees and to prize the traits that make them less desirable as employees. In addition, an older, more experienced worker may be more expensive ot just in terms of salary but also in terms of benefit costs. I have known of cases in which older employees were laid off just as their pension rights were about to vest. As a matter of fact, Disney did that to a good friend of ours after he had worked for them for many years.
As an older person, I have often been told by younger employees that I "don't look old." Nevertheless, I have been blatantly and frankly fired for my age by one employer and told by another, upon turning 50, that "There is a reason why men divorce their wives after they turn 50." In addition to stereotyping older employees, employers and co-workers often isolate them, act out the hostility they feel toward their own parents against them, to the other extreme treat them with exaggerated deference, or forget themselves and ridicule being old in front of an older worker. The worst and one of the most common forms of age discrimination is laying off an older worker first. If your friend is over 40, she may have been the victim of age discrimination, but she needs to talk to a lawyer, maybe several lawyers to find out if they think she has an actionable claim.
Some of the facts you describe suggest that the federal Older Workers Benefit Protection Act might apply. You have not, however, stated enough facts to determine whether it does or not.
Here are some websites that give info:
