So her "job" amounted to wandering the store, looking for customers who look like they aren't finding what they want, and then using their tablet to tell them where to go? That's something a high schooler should be doing! She should have "reinvented" herself by becoming something unique, something requiring special knowledge, like a pharmacy technician.
I have substantial sympathy, usually, for someone who's been laid off, but a 60ish adult whose education and skills have them qualified for a job suited for a high schooler or junior college student? What has she been doing the past 40 or 45 years?!
