National Labor Relations Board officials refused Friday to order an end to a two-week-old school bus strike in New York City.
Lawyers for the board issued a memorandum rejecting a complaint brought by a group of 20 private bus companies that argued the strike was illegal.
The decision mirrored past NLRB rulings and was widely expected, but will still disappoint some parents hoping for a quick end to a strike that has been hardest on students with disabilities.
Around 8,000 drivers and bus aides with Local 1181 of the Amalgamated Transit Union walked off the job Jan. 16 as part of a complicated labor dispute revolving around job-security provisions.
Just a fraction of New York City's public schoolchildren ride buses, but about a third of the 150,000 who do are special education students, including children who use wheelchairs.
The bus companies argued in their NLRB complaint that they were essentially caught in a dispute between the union and the city.
Federal law generally prohibits workers from striking against a secondary employer in order to punish a primary employer, but the NLRB said that doesn't apply in this case because both the city and the bus companies are primary employers.
Jeffrey D. Pollack, the chief lawyer for the New York City School Bus Contractors Coalition, said he intends to appeal.
"The bus companies will continue to do everything we can to get the buses rolling so we can get New York City's schoolchildren back to school safely," he added.
