The Seventh Circuit held that the record failed to contain sufficient evidence to support NLRB's determination that Columbia had violated NLRA, where language in the collective bargaining agreement gave Columbia the sole discretion to modify courses within its curriculum. Further, the NLRB erred in awarding the union bargaining expenses during its efforts to have Columbia bargain over reduction in credit hours, although on remand NLRB could grant certain expenses based on its unchallenged finding that Columbia had failed to bargain in good faith.
