Discuss the below in detail:
The owner of a manufacturing facility, staffed entirely by Mexicans, refuses employment to a white American manager because the owner is concerned that the Mexicans will only consent to supervision by another Mexican.
Newton's fire department has a minimum height and weight requirement for its firefighters. These requirements disqualify approximately 80% of all women, but only 5% of all men. Jane, who has wanted to be a firefighter all her life, applies for a position in the Newton Fire Department, but is not hired because she does not meet the minimum height and weight requirements. In these 2 situations, tell me whether illegal discrimination has occurred. If it has, is it disparate treatment or impact?
