DAH!!!
1) Just reading the title would have informed you that it's the police union taking the patriotic stand against the Antifa thugs.
2) As for the teacher unions, representing teachers in their Antifa criminal mob violence goes far beyond the school administrative infractions that any union can give them protection. Their criminal activity is not being protected by unions but by elected politicians and the political corrupted police-commissioners/police-chiefs they have appointed.
The Police Union was counter protesting the BLM Thugs that were posted outside an Officers house. The Police Union did not start anything. They did not go to a black neighborhood and protest down MLK Blvd. They were supporting a fellow Officer. Not making threats of violence.
Reading Is Fundamental

no gov’t employee should be represented by a union. This was a sensible rule until the 1940s. Calvin Coolidge & Ronald Regean weee right.
