The Court concurs with the Appellate Division that the parties’ dispute did not raise a scope-of-negotiations question and that the trial court therefore properly asserted subject matter jurisdiction. However, the Court reverses the Appellate Division’s judgment on the vested-rights claim. As the governing contracts made clear, a given teacher’s right to sick leave compensation did not vest until that teacher, having served the length of time required by the agreement, retired or otherwise separated from employment with his or her sick leave still unused. When the Board and the Association limited such compensation in their 2015 Agreement for the Association’s members, they did not infringe on a vested right. The cases on which the trial court and Appellate Division relied address issues distinct from those involved here and warrant no departure from the unambiguous contractual terms to which the Board and the Association agreed.
