Discrimination doesn't have to be so explicit. Saying "I'm going to fire everyone over 50" is obviously discrimination, but so is "I'm going to fire everyone near the top of the salary range for their job family". It has the same impact, but it's discrimination is cloaked behind a layer of misdirection. The law isn't so blind
Depends on the company, but even in ones that do, it's usually new hires are paid on the higher end of the band.
That means a junior engineer hired yesterday makes more than a junior engineer hired two years ago, but it doesn't mean that the junior engineer hired yesterday makes more than the staff engineer hired a decade ago
