On Jobs: Follows precedent in workplace racial discrimination cases

She ruled in favor of plaintiffs in only 3 of the cases. "Plaintiffs in employment discrimination cases lose a lot; they are notoriously hard to win," said an employment law expert.

In one case, Jackson declined to certify racial discrimination claims brought by two Black workers against defense contractor Lockheed Martin Corp as a class action that would have involved potentially more than 5,000 employees.

Jackson's rulings show that she followed Supreme Court precedent in analyzing cases brought under the federal law that prohibits employment discrimination, a claim that can be difficult to prove because plaintiffs rarely have direct evidence of bias.
