What Is Constructive Dismissal, and How Do You Avoid It?

Constructive dismissal is one of those phrases that worries owners without them being quite sure what it means. In short, it is when an employee resigns because of the way they have been treated, and argues that resignation should count as a dismissal. Here is what it actually means, and the practical ways to avoid handing someone a claim.

What constructive dismissal actually means

It happens when an employer does something serious enough to break the trust at the heart of the working relationship, and the employee resigns in response. Think a significant unilateral change to someone's role or pay, a failure to deal with a genuine grievance, or a pattern of treatment that makes their position untenable.

The employee is effectively saying: you left me no choice but to leave. If a tribunal agrees, the resignation can be treated as a dismissal, and you may have to defend it as if you had dismissed them.

First move

Treat any major change to someone's role, pay or treatment as something to handle carefully, not impose overnight.

The situations that most often trigger it

Common flashpoints include cutting hours or pay without agreement, demoting someone, ignoring a grievance, singling someone out, or letting bullying go unchecked. Rarely is it one dramatic act. More often it is a build-up that finally tips over.

The warning sign is usually there before the resignation: a grievance you have not dealt with, a change someone is unhappy about, a situation that has been left to fester. That is the moment to act, not after they have walked.

First move

If someone has an unresolved grievance or is unhappy about a change, deal with it now, before it becomes a resignation.

How to protect your business

You can make changes and manage people firmly. What protects you is doing it properly: consult before you change terms, deal with grievances promptly and fairly, and keep treating people reasonably even when the relationship is strained.

If you are already in a tense situation and worried a resignation is coming, get a clear read on it early. The right handling now is far cheaper than defending a claim later.

First move

Consult before changing terms, deal with grievances promptly, and get advice early if you sense a resignation coming.
