Groups met across the state and country Monday to remember the assassination 43-years-ago of Dr. Martin Luther King Jr. and to continue his work.
In Greenville supporters of workers' rights marched to the Willis building and had discussions on collective bargaining rights.
The group says they picked Monday because of its historical significance.
The day before Dr. King was killed in Memphis he gave a speech in support of that city's sanitation workers. They say workers today fight for some of the same basic rights.
Collective bargaining was prohibited in North Carolina in 1959.
