The School Reform Commission in Philadelphia got some recommendations from the Boston Consulting Group that would essentially wipe out collective bargaining. BCG wants principals to be able to hire and fire at will; they want teachers to have no job security. Given its druthers, according to this account in The Notebook, the business-dominated School Reform Commission would like to get rid of all job protections and simply impose a contract. The SRC and BCG think that they can attract better teachers to Philadelphia if they break the union. Like other corporate reforms, they have zero evidence for their hope.
Just another sad chapter in the ongoing effort by corporate-style reformers to get rid of collective bargaining for teachers. Very likely the BCG proposed the vast expansion of charters as another way to bypass unionized teachers.
