Biography
Sylvia Weiner was named among workers facing court proceedings in the grocery-strike report published May 24, 1930. The article establishes a labor-related prosecution, without an individual sentence or exact physical custody interval. Daily Worker, May 24, 1930, page 5.

Page 2 announces an April 4 welcome on her return from prison, expressly saying she served a thirty-day sentence for activity in a cafeteria strike. This documents actual service, distinct from a merely threatened term. The issue provides no exact arrest or physical discharge day and does not establish that this was the separate May 1930 grocery prosecution.
