Romance at Work: When Does a Private Relationship Become an Employer's Business?
The car steamed up. Then it started rocking.
It might sound like a scene from a comedy, but this was a real situation one of our clients had to manage.
Two employees had started a relationship. That, in itself, was not the problem. Their behaviour at work was.
Colleagues had become increasingly uncomfortable with their intimate behaviour during the working day. Their lunchtime activities in a car in a public car park were also attracting attention from neighbouring businesses.
Following an investigation and disciplinary process, both employees were ultimately dismissed.
This was an extreme case. Many workplace relationships cause no difficulty at all. But it illustrates an important question for employers: when does a private relationship become a workplace issue?
The relationship itself is not usually the issue
People meet at work, friendships develop and, sometimes, romance follows. A consensual relationship between colleagues does not automatically require an employer to intervene.
The focus should be on any effect on conduct, performance, colleagues, decision-making, confidentiality or the organisation's reputation - not on personal opinions about the relationship.
Address the workplace behaviour. Do not judge the relationship.
Professional boundaries still apply
There is a difference between being in a relationship and behaving inappropriately at work. Repeated intimate touching or sexualised behaviour can make colleagues, customers or clients uncomfortable.
For a minor conduct concern, a private conversation may be enough. Explain what has been observed, listen to the employees involved and make the expected standards clear. Serious allegations, or behaviour that continues after a clear instruction, may require a formal process.
Do not assume behaviour is harmless simply because the couple welcome it. Sexualised conduct can potentially amount to sexual harassment of someone who witnesses it, even where it is not directed at them.
When one person manages the other
A relationship needs particular care when one person influences the other's pay, workload, holiday requests, appraisal or promotion. Even where both believe they are acting professionally, colleagues may question whether decisions are impartial.
Consider whether another manager should take responsibility for those decisions. Any changes should be discussed with the employees and based on genuine business needs, rather than automatically moving the more junior person or making assumptions based on gender.
An imbalance of power also deserves attention. Employees need a safe way to raise concerns without having to approach the person they are in a relationship with.
Conflicts of interest and confidentiality
A relationship does not give either employee permission to access or share information they would otherwise have no right to see. Information about pay reviews, redundancies, disciplinary matters or a colleague's health must remain confidential.
Where disclosure of a relationship is necessary to manage a genuine conflict of interest, explain what must be disclosed, to whom and why. Collect only the information needed to manage the workplace risk, avoid unnecessary intimate details and restrict access appropriately.
What happens if the relationship ends?
The most difficult issues sometimes arise after a relationship has ended, particularly where former partners still work closely together.
Repeated personal messages, pressure to resume the relationship or unwanted physical contact should not be dismissed as a private disagreement. A previous relationship does not mean that future attention is welcome, and unwanted sexual conduct may amount to harassment.
Take concerns seriously, establish the facts promptly and consider what support or protective arrangements are needed. Do not assume that someone raising a concern should be the person moved or disadvantaged.
Employers in Great Britain already have a legal duty to take reasonable steps to prevent sexual harassment. From 30 October 2026, that duty will be strengthened to require all reasonable steps. Reviewing risks, policies, reporting routes and training should not wait until a complaint is made.
What if colleagues complain?
There is an important distinction between colleagues disapproving of a relationship and colleagues being exposed to inappropriate behaviour.
Listen without making assumptions. Establish what happened, when it happened and how it affected the people involved. Keep information as confidential as a fair investigation allows, and discourage gossip or speculation. Concerns about harassment should be handled fairly and sensitively, not brushed aside as someone being oversensitive.
Can disciplinary action be appropriate?
Potentially, yes. The concern should be the specific conduct or breach of a reasonable workplace rule, rather than simply the existence of a relationship.
Depending on the facts, this might involve inappropriate behaviour, leaving duties without permission, harassment, a breach of confidentiality or refusing a reasonable management instruction.
Investigate, explain the allegations, give each employee an opportunity to respond and follow a fair disciplinary procedure, including the right to be accompanied at a disciplinary hearing and the right to appeal. Consider each person's circumstances individually and apply standards consistently. Dismissal is not automatic, however striking the allegation may be.
Set clear expectations before a problem develops
A proportionate relationships-at-work policy can help explain professional boundaries, disclosure of relevant conflicts and how concerns will be handled. It should work alongside your policies on conduct, confidentiality, bullying and sexual harassment.
Policies alone are not enough. Managers need the confidence and training to recognise concerns, respond appropriately and have sensitive conversations. Employees need clear reporting routes, including an alternative contact where their manager is involved.
A private relationship is not automatically an employer's business. Its impact on the workplace can be.
