Baltimore City-contracted security officers are set to go on strike over unfair labor practices (ULP) starting Thursday, Aug. 6 at 12:30 p.m. This is the second time the non-union security officers will strike over the alleged unfair labor practices of heat and wage theft violations against their employer, city contractor Metropolitan Protective Services (MPS). Among the ULP allegations, the security officers accuse MPS of failing to ensure a pregnant officer received her legally required heat-related break or sufficient water when the heat index was 104 degrees. If so, those failures leave officers vulnerable to heat stress and its associated illnesses, including heat stroke and exhaustion. After the first strike on April 9, non-union security officers filed unfair labor practice charges alleging six MPS officers were fired, sent home, or removed from the schedule.
