This just in from a Jesse Bacon, concerned parent of a child at Perelman Jewish Day School in Philadelphia:

Perelman Jewish Day School teachers have been unionized for nearly four decades. Suddenly in March the schools board of directors withdrew recognition of the teachers’ union. The school took unilateral action to bust their teachers’ union, as the Hobby Lobby case was being heard in DC and on the eve of the anniversary of the Triangle Shirtwaist fire and while Philly’s teachers’ union is also under attack.
Fortunately, the union is fighting back, but there is a lot of fear and demonstrating broad community support, from Jewish folks, from people with a tie to the school, and from people who care about education. The school is hiding behind a religious exemption while claiming that Jewish law on respecting labor doesn’t apply.

I’ve been involved in similar efforts at my alma mater, Seattle University, in urging the administration that their religiously-rooted passion for social justice is at odds with their claims that their religious status also exempts the university from union requirements. Luckily, the courts threw their case out on its merits. Treating teachers fairly is just as part of religion and social justice as the rest.
