Employment arrangements rarely remain the same for long. As businesses grow and operational needs change, employees may take on new responsibilities, adjust their working hours, receive pay increases, or move to a different work location. While these changes may seem straightforward, employers can face unnecessary risk if agreed changes are not properly documented.

Changing employment terms? Why employers need to get contract variations right

For many small and medium-sized businesses, employment arrangements evolve naturally over time. A part-time employee may increase their hours, a team member may be promoted, or a business may relocate to a new site.

When these changes occur, it's important to remember that employment contracts are not simply administrative paperwork. They set out the agreed terms and conditions of employment between an employer and employee. Any changes to those terms should be carefully documented to ensure both parties understand and agree to the revised arrangement.

 

Employment contracts are not static

It's common for employment arrangements to change throughout the course of employment. Examples include:

  • Changes to hours of work

  • Promotions or changes to position titles

  • Pay increases or remuneration adjustments

  • Changes to award or enterprise agreement classifications

  • Relocation to another workplace

  • Other agreed changes to employment conditions

While some changes may appear minor, they can have a significant impact on an employee's terms of employment. Documenting these changes helps ensure there is a clear and accurate record of what has been agreed.

 

Contract variations require agreement

One of the most important principles for employers to understand is that contractual terms generally cannot be changed unilaterally.

Where a change affects an employee's contractual employment conditions, both the employer and employee should agree to the proposed variation. A written record helps confirm that agreement and provides clarity about when the change takes effect and what it involves.

Without a formal process, misunderstandings can arise about what was discussed, what was approved and when the change was intended to commence.

Having the employee acknowledge and accept the variation helps protect both parties and supports transparent workplace practices.

 

The risks of informal arrangements

Many employers rely on verbal discussions, meeting notes or email exchanges to communicate changes to employment arrangements. While these conversations are often well-intentioned, informal records can create challenges later.

Potential risks include:

  • Disputes about what was agreed

  • Confusion regarding pay rates or hours of work

  • Difficulty demonstrating the agreed terms if questions arise

  • Administrative and compliance issues caused by inconsistent records

For example, a manager and employee may verbally agree to reduce working hours, only for each party to later have a different understanding of the arrangement. Similarly, a promotion involving new responsibilities and remuneration may be difficult to verify without a formal record.

Clear written documentation is not only good risk management but also good business practice.

 

Introducing the new contract variation letter

To help employers correctly document agreed changes, My Business Workplace has introduced a new Contract Variation Letter template.

The template is designed to confirm and record changes to an existing employment contract and can be used for variations such as:

  • Employment status*

  • Hours of work

  • Award classification

  • Rate of pay

  • Position title

  • Location of work

  • Other contractual employment conditions

*Where an employee converts from permanent to casual employment, or vice versa, a new employment contract should be issued rather than using a variation letter.

The template formalises agreed changes and includes employee acceptance, helping employers maintain accurate and consistent employment records.

It is also important to note that the Contract Variation Letter cannot be used to alter legislative minimum entitlements or statutory employee rights. For example, it cannot be used to remove an employee's entitlement to paid leave, workers' compensation rights or minimum wage protections.

 

A simple step that can prevent bigger problems

Regularly reviewing employment arrangements is an important part of effective people management. When changes occur, employers should ensure they:

  • Properly document agreed variations

  • Obtain employee acceptance where required

  • Maintain accurate employment records

  • Seek professional guidance when necessary

Taking these steps can help reduce the risk of disputes, improve record-keeping and provide greater confidence that workplace arrangements are being managed appropriately.
