According to CBS affiliate KDKA, teachers in the Pittsburgh Public Schools District are planning to go on strike Friday.

A statement by the Pittsburgh Federation of Teachers said that Superintendent Dr. Anthony Hamlet has been served with a strike notification.

According to the notification, more than 3,000 “professional, paraprofessional, and technical clerical workers will go on strike starting Friday, March 2.”

Act 88 states that the school district much be given a 48-hour notice of a strike.

“We provided the district with a 96-hour notice in order to provide extra time for our students’ parents to secure childcare for their children, our students, and to provide the parties’ with sufficient time to reach tentative agreement on new contracts for the three bargaining units prior to the commencement of the strike.  We are hopeful that that extra time will allow the Federation and the District to work together to reach a fair agreement that both recognizes the professionalism and hard work of our members and serves the needs of our students and school system,” Pittsburgh Federation of Teachers President Nina Esposito-Visgitis said.

KDKA reports that the sides are at a stalemate over the ability of principals to make teacher assignments within individual schools.

Last week, the union and the school district met for nine straight hours without a resolution.
