State and federal laws protect employees and job applicants from discrimination. For example, it is illegal for an employer to discriminate against an employee or a job applicant on the basis of his or her race, gender, pregnancy, age (40 or older), disability or membership in another legally protected class.
It's common for a large company to have bylaws and processes to follow throughout their organization. Bureaucracy keeps a uniform approach across multiple offices and time zones and keeps the brand universal when different people are running the show. Sometimes those rules are a little too rigid, though, and they suppress individual rights.
Federal laws prohibit job discrimination based on an employee's or applicant's race, color, sex, age (40 or older), religion, national origin or disability.
