Annual Labor Day Luncheon. Chicago is the home of the American labor movement, so it is fitting that the Labor Day weekend officially begins with the annual luncheon, hosted by the Chicago Federation of Labor and the CFL Workers Assistance Committee. Sponsorship packages and tickets are currently available. The deadline to place an ad in the Labor Day Solidarity Book is Friday, August 7. Registration begins at 11 a.m.; the luncheon begins at noon. Contact: Nora Cay Ryan, 312.222.1000
