A quick history lesson: In 1969, Medical College Hospital fired 11 employees after they contacted a New York healthcare union. Those employees, led by nurse's aide Mary Moultrie and local civil rights activist Bill Saunders, were seeking equal treatment for African Americans, who were being systematically denied opportunities for career advancement and pay increases. In response to the firing, they launched a strike that lasted 113 days and drew the attention of thousands of protesters. National civil rights leaders, including Coretta Scott King, packed the streets, eventually earning a few concessions from the hospital, including the rehiring of the 11 workers and a change in employment policies. Never heard this story before? Well, then this sign's for you: In October, the Preservation Society of Charleston placed a historic marker on the Medical University of South Carolina campus commemorating the protests. Our hats are off to you, Mary Moultrie.
