What happens to pay rates after the nominal expiry date?

Some agreements refer to a pay rate schedule that refers to specific dates for pay rate increases. If a new agreement has not been negotiated or terminated there is no obligation on the employer to offer further increases until the modern award rates surpass the employees’ pay rates. Some agreements have a mechanism for continued pay increases after the nominal expiry date either by reference to the annual Fair Work Commission determination or at a continuing set percentage each year.
