Mayor Bill de Blasio faces challenging negotiations with 152 unions representing about 300,000 municipal employees, primarily focusing on the United Federation of Teachers (UFT), whose contract has been expired since 2009. Current salary increases for teachers, driven by the Triborough Amendment, totaled $1.2 billion from 2009 to 2013 despite the lack of a new contract, reflecting an average raise of 2.8% annually. Looking ahead, the city must consider modifying contract provisions to prevent future lapses in negotiations and ensure more sustainable labor agreements.
