In County of Lehigh v. Pennsylvania Labor Relations Board, 507 Pa. 270, 277, 489 A.2d 1325, 1329 (1985) the Supreme Court took a practical approach to infringement questions. Citing Ellenbogen and Commonwealth ex rel. Bradley v. Pennsylvania Labor Relations Board, 479 Pa. 440, 388 A.2d 736 (1978), it stated that "county commissioners are not prohibited from negotiating 'wages, hours and other terms and conditions of employment' provided such terms do not impinge upon judicial control of hiring, discharge and supervision in some concrete manner." County of Lehigh, 507 Pa. at 278, 489 A.2d at 1329. It explained: For example, a shorter work day, increased vacation time or additional paid holidays might be considered in return for a smaller wage increase. Such a compromise may be acceptable to the county commissioners and the union. However, the decrease in total work hours might adversely affect the administration of justice. The county commissioners must consult with the judges in order to ascertain the effect such a proposal may have upon the court if the resulting collective bargaining agreement is to pass constitutional muster. If it is determined that there would be no adverse impact there is no reason why the proposal should not be embodied in the collective bargaining agreement. It would be contrary to the public interest to bar such terms on the ground that they may impair the judges' "supervisory" authority in the abstract when the simple solution of prior consultation with the judges themselves is available. Id. at 279, 489 A.2d at 1329 - 1330.
