AML starts on the day after the Ordinary Maternity Leave (OML) period finishes.
An important difference between OML and AML is the extent of your right to return to work at the end of your maternity leave.
At the end of OML, you have the right to return to your old job. At the end of AML your right to return is slightly different. You have the right to return to your old job, but if it is not reasonably practicable for the employer to offer you your old job back, you must be offered appropriate similar employment, on no less favourable terms, and with your seniority and pension conditions unaffected.
Statutory Maternity Pay (SMP) or Maternity Allowance (MA) are payable, for those who qualify, for the first 39 weeks of maternity leave. This means that the first 13 weeks of AML will be paid if you qualify for SMP or MA. The remainder, if you take it, will be unpaid leave.
Throughout your maternity leave, you will build up annual leave under your employment contract. Adding some annual leave to the end of your maternity leave is one way of extending your time at home once your allowance of paid maternity leave has run out.
Any employer occupational pension contributions must continue to be paid in full during maternity, paternity and adoption leave throughout the time when the leave is paid (whether through statutory or contractual maternity pay). Pension contributions usually stop during any periods of unpaid leave. The whole of the leave period – paid and unpaid – must be taken into account when assessing length of service for occupational pension purposes.
Your employer must not discriminate against you while you are on any part of your maternity leave. If you feel that you have been discriminated against while on maternity leave, seek advice from your union or a legal specialist.
Your employer is not usually obliged to carry on providing you with child care vouchers under a salary sacrifice scheme them during your maternity leave.
At any stage after the first two weeks of maternity leave (four weeks for a factory worker), you have the right to end your maternity leave and opt into the Shared Parental Leave system, as long as both you and your partner qualify. For more information, see workSMART's Shared Parental Leave section and the Acas guidance on Shared Parental Leave (PDF, 753KB). Also see SPLASH, a web portal devised by a group of legal advisers and charities, including Working Families and Maternity Action, providing clear advice on the new Shared Parental Leave rights.
