Contract negotiations between NetJets management and the leadership of Local 1108, which represents the fractional provider’s pilots, seem to have gone from bad to worse, according to the union. The union said that mediated negotiations last month didn’t bring the two groups together but split them farther apart. NetJets management declined to comment. The union also sent strike ballots to its membership last month, which would give authorization to strike if the pilots are released for self-help. At press time, the National Mediation Board had put the remaining six days of bargaining sessions in “abeyance” until both NetJets management and pilots jointly agree to come back to the table.
