Activists pushing for racial equity have continued to pressure the Minneapolis Park Board, forcing meetings into temporary recess and even showing up at the doorstep of Park Superintendent Jayne Miller.

The most outspoken and persistent critics — a trio of present or former park workers with grievances, supported by activists from the Minneapolis NAACP and other activists — accuse the park system of racial bias in its hiring, promotion and discipline of staff.

Their accusations and chanting in board meetings have grown so frequent that the Park Board now has a dedicated Web page covering 17 related topics.

In one case, the board has sent a former employee a warning to stop referring to park employees as “house slaves” or “tokens” or risk banishment from future meetings under the board’s anti-discrimination and anti-harassment policies.

Commissioner John Erwin said he will ask the board committee he chairs on Wednesday to adopt a set of decorum standards for board meetings. Violation of those standards would allow park police to remove the offender. He said he’s doing so because no clear standards exist.
