What this means

SMP can run for up to 39 weeks, but Statutory Maternity Leave can run for 52 weeks. That is why a full year off often means a paid period followed by an unpaid tail.

What this page is checking

You can qualify for Statutory Maternity Leave from day one as an employee, but SMP needs the separate earnings and service tests. If you fail SMP, Maternity Allowance may still matter.
