Chicago parking attendants begin strike, union says it may expand Wednesday

A strike by Chicago-area parking attendants represented by Teamsters Local 727 began Tuesday and is expected to expand Wednesday, when union leaders say all represented attendants could be off the job. The union says the strike will roll out in waves affecting about 200 locations, and that it represents about 1,200 workers, including staff at McCormick Place and O'Hare airport. The union says the contract offer does not keep pace with inflation and rising health care costs.
