EEOC age discrimination provisions specify workers 40 and older (https://en.wikipedia.org/wiki/Age_Discrimination_in_Employme...)

I agree that it's distasteful but it's not actually illegal in the US (and of course poster is in CA.)

does the EEOC apply to CA?

EEOC does not but Canadian Human Rights Act does, and it forbids discrimination on the basis of age, unless it is proven to be BFOR (bona fide occupational requirement).
