What A Fundamental Breach Means
Your employer changed something you thought was a core part of your job.
Fundamental breach is the starting point of the legal test behind most constructive dismissal claims, so it is worth understanding clearly before you decide what to do next.
What It Means
It refers to a breach of a core, essential term of your employment contract, rather than a small or peripheral one, such as pay, job title, or basic reporting structure.
The word fundamental is doing real work here. Courts distinguish between changes that strike at the heart of your role and adjustments that, while unwelcome, do not.
Why It Matters To You
This is the first of several conditions courts weigh when deciding whether a resignation can be treated as constructive dismissal, alongside how serious the breach was and how you responded.1
Identifying clearly which specific term was broken, rather than describing general unhappiness, strengthens how your situation can be explained.
Which Terms Are Considered Fundamental
Pay, your actual job duties, and who you report to are commonly treated as core. A change to any of these without your agreement is worth examining closely.
Read about repudiatory breach for the related seriousness requirement, and constructive dismissal for how these ideas combine into a full claim.
If you resigned because of a change like this, check your 60-day window on the deadline calculator.
Telling us which specific term your employer changed helps us see whether it touches the core of your contract.
Common questions
How do I know which terms of my contract are fundamental?
Pay, job role, and reporting structure are commonly treated as core terms. Minor administrative details usually are not, though the full context of your specific contract still matters.
Is a single missed benefit enough on its own?
Usually not, unless that benefit was central to your agreement. A fundamental breach generally involves a change to something that goes to the heart of why you took the job.
