Requires employers whose employees are subject to contracts that are amendable and do not expire to provide earned sick leave.

This bill requires employers to provide earned sick leave to workers covered by union contracts that are "amendable" (allowing changes without expiration) rather than only those that expire. It directly affects employees under such contracts, ensuring they receive sick leave benefits as defined by New Jersey's Earned Sick Leave Law. The key provision clarifies that sick leave rules apply when a contract becomes amendable, not just at expiration, and preempts conflicting local ordinances. It also explicitly states the law does not reduce existing union benefits or collective bargaining rights.
