The specific action taken by the employer and when it occurred.
You can have a grievance without losing your job.
Warnings, suspension, reduced hours, demotion, changes to duties and other harmful employer actions can matter even while employment continues.
You do not need to lose your job before employer action can become a legal problem.
Unjustified disadvantage concerns employer action that negatively affects your employment while the employment relationship continues. The practical effect matters: a warning may influence later dismissal decisions, reduced hours may cut income, and removal of duties may alter status or career progression.
The useful comparison is often the position before and after the employer's action. Identify what changed, why it changed, how the decision was made and what concrete disadvantage followed.
What to identify
The disadvantage to your employment, such as pay, hours, duties, status, opportunities or disciplinary record.
The employer's reason for taking the action and the evidence supporting it.
Whether the action and process were what a fair and reasonable employer could have done in the circumstances.
Get these straight before the argument gets bigger.
What employer action changed your position or conditions?
What practical disadvantage did it cause?
What reason and process did the employer use?
Build the claim around the actual disadvantage
Name the decision
Identify the warning, roster change, suspension, demotion, duty change or other employer action precisely.
Show the before and after
Use rosters, job descriptions, pay records, correspondence or organisational material to show the practical effect.
Challenge promptly
Ask for the reason, supporting information and correction or reconsideration while the issue is current.
Preserve escalation options
If the action is not corrected, make sure any personal grievance is raised within the applicable time limit.
Things worth looking at closely.
- A warning unsupported by the investigation
- Hours or duties removed without a proper basis
- Suspension continuing without review
- A material complaint is ignored
- A detrimental change is presented as merely administrative
Ways employees accidentally make the problem harder.
Describing the workplace as generally unfair without identifying the employer action being challenged.
Assuming a warning has no consequence because pay has not changed yet.
Allowing a harmful temporary arrangement to continue indefinitely without asking when it will be reviewed.
Combining many unrelated complaints so the core disadvantage becomes difficult to identify.
What a useful result can look like.
Removal or correction of an unjustified warning
Restoration of hours, duties or status
Compensation or wage-related remedies where established
Negotiated resolution while employment continues or as part of an exit
Unjustified disadvantage
Do I have to be dismissed?
No. Unjustified disadvantage is specifically concerned with unjustified employer action short of dismissal.
Can I challenge a warning?
Potentially. A warning can materially affect employment and later decisions, so its justification can matter.
Can reduced hours be a grievance?
Potentially, depending on the agreement, the reason, process and practical effect.
What is the usual time limit?
Most personal grievances need to be raised within 90 days, so do not assume an ongoing employment relationship means there is no urgency.
Most disputes move through the same basic sequence.
- 1Preserve
Documents, dates, evidence and the deadline.
- 2Raise
Put the actual grievance or response clearly.
- 3Resolve
Negotiate or mediate where a sensible resolution is available.
- 4Escalate
Use the ERA or Court where the dispute cannot be resolved.
