Proxy advisory firm Glass Lewis on Tuesday recommended shareholders vote against the election of three directors - Dave Calhoun, Akhil Johri and David Joyce - to planemaker Boeing's (BA.N) board.
Boeing was not immediately available for a comment. Calhoun has said he will step down as CEO of the embattled planemaker at the end of the year.
Johri and Joyce serve as chairs of the Boeing board's audit and aerospace safety committees, respectively.
