A San Francisco public relations firm has been hired to track down more than 100,000 California women who may be eligible to share $26 million in unemployment benefits they were wrongfully denied between 1968 and 1976. Some women were denied unemployment benefits during that period because they were not the sole or major source of their families’ income. The public relations firm of Solem & Associates said applications have been distributed to post offices throughout the state in hopes that eligible women will pick them up and file claims. Eligible women may receive as much as $1,200 each, although most will receive less, according to a spokeswoman for the state Employment Development Department. They have until Aug. 31 to file applications.
