It's been called the "nuclear" option.
On Monday afternoon a coalition of education groups called on the Philadelphia School District to bypass negotiations and unilaterally impose new contract terms on the district's teachers.
The groups, led by Philadelphia School Partnership and PennCAN, specifically want the district to do away with teachers' union seniority provisions that give teachers with more years of experience their preference among available positions.
Instead, these advocates say the district should implement a system of 100 percent "mutual consent," where principals and prospective teachers agree on every new placement. This system — referred to within the district as "site selection" — is already in place in 169 of the district's 212 schools.
