What is a “protected class?”
edit: wiki lists 10 not 9
So, “sex” is a protected class, and the protection applies to everyone. There have been cases protecting males from discrimination on the basis of sex (for example - where a state had a higher minimum drinking age for men than women).
The federal ADEA (the Age Discrimination in Employment Act) only creates a right of action for people over 40.
It’s a weird one for sure. I wonder, if age were a suspect classification like sex, if the ADEA itself would be unconstitutional.
