"Scabs" are a type of protective covering that forms over a wound as it heals. They are made up of dried blood, tissue, and other fluids that help protect the underlying skin from infection and further injury. Scabs are a natural part of the healing process and usually fall off once the skin underneath has fully healed. In the context of labor disputes, "scabs" refers to workers who continue to work or take the jobs of those on strike. This term is often used negatively, as it can undermine the efforts of striking workers who are advocating for better conditions or pay. The use of scabs can prolong labor disputes and create tension between workers and employers.
