Owen Sound Police had to intervene several times Thursday at the Family Health Organization strike location.
Local and out-of town-picketers set up along the sidewalk on 1st Ave. W at 14th St. W.
Several times, picketers refused to move out of the way of vehicles attempting to enter the property, and there were confrontations with drivers.
Police were needed to mediate disputes between the parties. Investigations are continuing into several incidents.
30 OPSEU staff at the doctor-owned Family Health Organization in Owen Sound have been on strike since May 22.
