Creating a union constitution

What must or may be included

Incorporated Societies Act requirements

Every incorporated society, including those that register as a union, must have a constitution. This is an important legal document that sets out your society’s purposes, what it does and how it operates.

The Incorporated Societies Act 2022 (ISA) specifies what must be included in a society’s constitution.

If you want to change the way your society operates, you can update your constitution. Your society’s existing constitution must set out how to make changes, so follow these processes to update or replace your constitution. Any change you make will only take effect once it has been registered with the Registrar of Incorporated Societies.

Employment Relations Act requirements

In addition to the requirements of the Incorporated Societies Act, the Employment Relations Act 2000 (ERA) has some specific requirements for a union’s constitution.

It must be:

• democratic
• not unreasonable
• not unfairly discriminatory or prejudicial
• not contrary to law.

Objects or purposes

Your union’s constitution must define its purpose or ‘objects’. They:

• must include an object, or a combination of objects, to promote members' collective employment interests.
• should state all of the union’s objects, in terms that satisfy both its current and longer-term intentions. (A union cannot legally undertake activities that fall outside its objects.)
• may also include objects related to members non-employment interests, for example, providing scholarships for the education of member's children, running holiday homes, securing discount arrangements with retailers.

Membership provisions

A union’s constitution or rules must also define who may join as a member. Membership can be defined in one or more of the following ways:

• Employees in a particular occupation, for example, plumbers or cleaners
• Employees in particular industries or sectors, for example, the manufacturing, retail, or construction industries, or the public sector
• Employees in a particular enterprise or workplace, for example, employees of Barry's Catering Ltd
• A combination of these approaches
• In other, more general terms.

Unions may have overlapping membership coverage. There is nothing in the ERA to prevent an employee joining more than one union.

Unions should be aware that there are close links between membership rules in your constitution and union access rights, which means there may be confusion if membership rules are unclear.

Unions should also note that union members are automatically bound by collective agreements negotiated by the union. Some employees may not want the union to represent them for the purposes of collective bargaining. If so, unions should have another category of person (avoiding the word 'member') who can join the union for purposes other than collective bargaining.

The membership rules must:

• define clearly who can become a member
• set out how people can join the union
• set out how people cease to be members of the union. That is, how members can resign, and how (and in what circumstances) they can be expelled.

Fees

Union constitutions generally specify some means of fixing and collecting union fees.

Members’ meetings

The constitution must cover how:

• meetings are called,
• members (or their delegates) can participate in the meetings,
• meetings are conducted (chair, quorum, etc), and
• voting takes place.

The constitution must also contain provisions for holding a secret ballot (ERA).

Officers

The constitution must specify how union ‘officers’ are elected.

They should also state who the union's officers are, their roles, who may seek election to officer positions (often restricted to members), and when and how an officer can be removed from office.

The traditional union ‘secretary’ may be an elected ‘officer’ but is often an employee who is appointed by the executive committee.
