Law firm Goldberg Segalla allegedly told its roughly 1,000 employees that they couldn’t share details of their salary with each other and had to settle claims with a federal agency, Above the Law reported this week.

The Am Law 200 firm, which has an office in Baltimore, has a National Labor Relations Board practice and releases alerts on NLRB opinions.

The firm had employees sign a “confidentiality agreement” that included language that any employee who shared salary information with colleagues would be terminated, even though it is illegal to impede salary talk under the Lilly Ledbetter Fair Pay Act, Above the Law reported.

Goldberg Segalla has more than 400 attorneys from Los Angeles to London, including a large New York presence, and 13 attorneys in Baltimore, according to the firm website.
