Age Discrimination

The Barton Law Firm sues employers who discriminate against employees based on the employees' ages, and sues employers who retaliate against employees for opposing age discrimination.

Here are legal citations and information you might find helpful:

There are two ways to discriminate: by disparate treatment and by disparate impact. Disparate treatment occurs when an employer treats an employee who belongs to a protected class less favorably than other employees. Disparate impact occurs when an employer has a neutral employment practice that falls more harshly on members of a protected class.
