The National Labor Relations Board has withdrawn its complaint against Honeywell for locking out its workers for 10-months.

Peter Robb, the general counsel for the NLRB, directed the agency to withdraw its complaint and cancelled the May 2018 trial on Thursday.

The NLRB issued a complaint against Honeywell last year alleging its 10-month lockout of employees violated federal labor law.

Workers were locked out in May 2016 in a contract dispute over issues such as health care coverage and subcontract work.

UAW members voted in favor of a new 5-year agreement in February 2017.
