Employee Relations: Handling Grievances, Discipline & Difficult Conversations

2 min readPublished 29 Jul 2026

Employee Relations (ER) is the day-to-day working relationship between an organisation and its people — and handling the moments when things go wrong. It's often the most sensitive, judgement-heavy part of HR.

What ER covers

Grievances and complaints, disciplinary and conduct issues, capability and performance concerns, absence and wellbeing, conflict between colleagues, and supporting managers to have difficult conversations — all fairly, consistently and legally.

Grievances

A grievance is a concern, problem or complaint raised by an employee. Handle it under a clear grievance procedure aligned to the ACAS Code: listen, investigate impartially, hold a meeting (with the right to be accompanied), decide, and offer an appeal. Take every grievance seriously and keep records.

Discipline & conduct

Where conduct falls short, follow a fair disciplinary process: investigate first, decide if there's a case to answer, hold a hearing (with accompaniment), consider the facts and any mitigation, apply a proportionate outcome (from informal chat to warning to dismissal for gross misconduct), and allow an appeal.

Difficult conversations

Great ER means handling hard conversations with clarity and empathy: prepare and stick to facts, be direct but respectful, listen, focus on behaviour and impact (not the person), agree clear next steps, and follow up. Avoid ambushing people or avoiding the issue until it festers.

Coaching managers

Much ER work is enabling managers to handle issues well — coaching them on process, fairness and how to have the conversation, rather than doing it all for them. This builds capability and consistency.

Wellbeing and mediation

Not everything needs a formal process. Early, informal resolution and mediation often work better for interpersonal conflict, and signposting wellbeing support (EAPs, occupational health) is part of good ER.

Confidentiality and fairness

ER handles highly sensitive information. Protect confidentiality, stay impartial, treat like cases alike, and document decisions and rationale.

Put it to work

Plan how you'd open a difficult conversation about repeated lateness — factual, empathetic, with clear next steps. Then run a real ER scenario in the HR Simulations.

Frequently asked questions

What is the difference between a grievance and a disciplinary?

A grievance is a concern raised BY an employee (they feel wronged). A disciplinary is a process the employer runs when an employee's conduct or performance falls short. Both must follow a fair, ACAS-aligned procedure.

What is the right to be accompanied?

Employees have a statutory right to be accompanied by a colleague or trade union representative at formal grievance and disciplinary hearings. Denying it undermines fairness and the ACAS Code.
