Types of work: unmeasured work

Relevant legislation

The legislation that applies to this page is as follows:

  • National Minimum Wage Regulations 2015, regulations 44 to 50

If a worker is performing work that does not fit into the definitions of salaried work, time work or output work then they are performing unmeasured work.


Unmeasured work may include work where there are no associated specified hours or times when the work must be undertaken or when the employer only needs the worker to work when needed or when work is available.


Workers performing unmeasured work are paid by reference to either;

  • The actual hours worked ; or
  • The time specified in a daily average agreement (NMWM07120).

There are some simple examples which can help indicate whether a worker is performing unmeasured work or not (NMWM07110).
