Why Handling Difficult Conversations Matters

A conversation you dread for weeks can be resolved in 15 minutes if you prepare properly (peer-reviewed research). A conversation you wing can damage relationships for months.

Most workplaces avoid difficult conversations altogether (apa.org). Managers postpone feedback. Teams sidestep conflict. Problems fester until they explode, costing organisations missed deadlines, broken trust, and talented people leaving because they never received honest feedback about their performance.

Handling difficult conversations at work isn't about being harsh or confrontational. It's about being clear, kind, and direct. When done well, these conversations strengthen relationships because people know where they stand and understand what needs to change.

At MacMillan Training Partnership, we work with managers across the UK who've learned that difficult conversations are a skill, not a talent. This guide walks you through the exact steps to handle them with confidence, including specific phrases that work, common mistakes to avoid, and a follow-up process that ensures real change.

Prepare Before You Start the Conversation

The difference between a conversation that lands and one that falls flat happens before you open your mouth. Most people skip preparation, assuming they'll "figure it out" in the moment. That's when emotions take over and words come out wrong.

Preparation removes the guesswork and gives you a framework to return to if the conversation gets heated.

Clarify your objectives and outcomes

Before you schedule the conversation, write down exactly what you want to achieve. Not what you want to say, but what you want to happen as a result.

The objective isn't "tell them they're underperforming." It might be "understand why deadlines are missed and agree on a plan to hit them consistently" or "clarify expectations about communication in meetings and establish what good looks like."

Be specific. A vague objective like "improve their attitude" won't guide you when the conversation gets difficult. A clear objective like "agree on three specific changes to how they approach client calls" gives you something concrete to aim for.

Write down what success looks like. If this conversation goes perfectly, what will be different? Will they commit to a new approach? Will you both understand each other's perspective better? Will they have a clear action plan? This clarity prevents you from getting sidetracked when the conversation drifts.

Choose the right time and place

Timing matters more than most people realise. Never have a difficult conversation when either of you is rushed, stressed, or emotionally activated. A Friday at 4:45 p.m. when everyone's tired? Wrong time. First thing Monday morning when they're anxious? Wrong time.

The right time is when both of you have space to think. Mid-morning or early afternoon usually works. Give them advance notice if possible: "I'd like to discuss your recent project performance. Can we schedule 30 minutes on Wednesday?" so they're not blindsided.

The right place is private. Not in the open office where others overhear. A quiet meeting room where you can close the door and speak without interruption signals that the conversation is important and confidential. Privacy also matters for them, if they become emotional, they don't have an audience.

Difficult Conversation Scripts for Managers

Knowing what to say is half the battle. Most managers either go too soft, sugar-coating the issue so nothing lands, or too harsh, leading with criticism that puts people on the defensive immediately.

The scripts below follow a pattern: acknowledge, clarify, listen, agree on next steps. This pattern signals that you're not attacking them; you're addressing a specific situation.

Opening phrases that set the right tone

How you open determines whether they'll listen or shut down.

Strong openers:

"I want to talk about your recent work on the X project. I've noticed some things I'd like to understand better, and I want to work through them together."

This signals that you've observed something specific and you want their input, not just lecturing.

"I've been thinking about how to support you better in your role. I think there's a conversation we need to have about expectations. Can we talk through it?"

This positions the conversation as you trying to help them succeed, not as criticism.

"I noticed that [specific situation]. That's not how we usually handle this, and I want to understand what happened so we can figure out how to move forward."

This sticks to observable facts and opens the door for their explanation.

Openers to avoid:

"We need to talk about your performance." Too vague and ominous. They'll be defensive before you start.

"I'm disappointed in you." Makes it personal. They'll hear judgment, not feedback.

"Everyone's noticed that you..." Implies public criticism and makes them feel exposed.

"You always..." or "You never..." Absolute statements that feel like character attacks.

Phrases to avoid during the discussion

Avoid these:

"Honestly, I think you're not cut out for this role." A judgment about their capability that shuts down conversation.

"Other people have complained about you." Vague and accusatory, making them feel ganged up on.

"You need to do better." Not specific enough to act on.

"I shouldn't have to explain this to you." Condescending and demoralising.

"If you don't fix this, we'll have to let you go." A threat that belongs in formal performance management conversations with HR, not casual warnings.

Instead, stay specific and collaborative: "Here's what I've observed. Here's what needs to change. Here's how I'll support you."

How to Give Constructive Feedback at Work

Constructive feedback is specific, actionable, and focused on behaviour rather than character. It's the difference between "You're disorganised" and "The last three reports were missing the budget breakdown we discussed. Let's set up a template so you have a clear checklist before submission."

The feedback framework that works

A simple framework keeps feedback on track: observation, impact, and request.

Observation: Describe what you've seen or heard. Stick to facts, not interpretations.

• GOOD: "In the last three team meetings, you've interrupted others five times."
• BAD: "You're dominating meetings and not listening to anyone."

Impact: Explain what effect this has.

• GOOD: "When people get interrupted, they stop contributing ideas. We lose input from the team."
• BAD: "You're destroying team morale and making everyone hate you."

Request: Say what needs to change, specifically.

• GOOD: "I'd like you to pause after each person speaks and ask if anyone else has input before moving on."
• BAD: "You need to be a better listener."

Follow the framework in order. Observation first, so they understand what you're basing this on. Impact second, so they understand why it matters. Request last, so they know what to do about it.

Staying calm when emotions rise

Even with perfect preparation, emotions emerge. Someone gets defensive. You feel frustrated. The conversation gets tense.

First: pause. If you feel anger rising, take a breath. Don't respond while you're activated.

Second: name what's happening. "I notice this is getting heated. That's not what I want. Can we take a step back?" This signals that you're aware of the dynamic and want to reset.

Third: return to the objective. "My goal here isn't to make you feel bad. It's to make sure we're aligned on what needs to happen next. Can we focus on that?"

If they're emotional, let them be. Don't try to fix it. Silence is okay. Say, "I can see this is difficult. That's understandable. Take a moment." Then wait. Don't continue while they're highly emotional. Wait until they've settled.

Acas Guidance on Challenging Conversations

The Advisory, Conciliation and Arbitration Service (Acas) provides clear guidance on handling difficult workplace conversations fairly.

According to Acas guidance on challenging conversations, the foundation of any difficult conversation is fairness. Employees should know what's being discussed, why, and what the expectations are moving forward. Acas recommends giving advance notice of serious conversations when possible, allowing the person to prepare and bring support if needed.

Acas emphasises that these conversations should be two-way. You're not lecturing; you're discussing. This means giving the other person space to explain their perspective, ask questions, and contribute to the solution.

Documentation matters. After a difficult conversation about performance or conduct, write a brief note of what was discussed and what was agreed. This protects both of you and ensures clarity.

Acas also emphasises that informal conversations are different from formal disciplinary conversations. Informal conversations address issues early, before they become formal performance or conduct matters. The tone is supportive, not punitive.

If a conversation becomes formal, employees have the right to be accompanied by a colleague or union representative. Respecting this right signals professionalism and fairness.

Common Mistakes to Avoid

Most difficult conversations fail not because people lack good intentions, but because they make predictable mistakes.

Mistake 1: Waiting too long. The longer you wait, the bigger the issue becomes in your head. A single missed deadline becomes "they're unreliable." Address issues when they're small.

Mistake 2: Being too indirect. Some managers dance around the issue so much that the person leaves confused about what the actual problem is. Be direct. Name the specific behaviour or situation.

Mistake 3: Making it personal. "You're lazy" or "You don't care" are character judgements, not feedback. They trigger defensiveness. Stick to specific behaviours: "The last three reports were submitted after the deadline."

Mistake 4: Ambushing them. Springing a difficult conversation on someone with no warning puts them in survival mode. Give advance notice when possible.

Mistake 5: Not following up. The conversation ends, and nothing changes because there's no accountability. A difficult conversation that leads to change requires follow-up.

Mistake 6: Letting emotion drive the conversation. If you're angry or frustrated, postpone the conversation. You won't communicate clearly.

Mistake 7: Assuming you know why. You don't know their reasons. Ask. "The deadline was missed. What happened?" Listen to the answer. There might be a legitimate reason, a system failure, or a miscommunication.

Follow Up After the Difficult Conversation

The conversation doesn't end when you both leave the room. What happens next determines whether anything actually changes.

Within a day or two, send a brief email confirming what you discussed and what was agreed.

"Thanks for talking through the project delays yesterday. As we discussed, the plan is to submit reports by 3 p.m. on Fridays, with a checklist to confirm all sections are complete. I'll check in with you next Friday to see how it's going."

This confirms the agreement, shows you're taking the commitment seriously, and sets a clear check-in date.

Schedule a follow-up conversation a week later, long enough for them to try the new approach, short enough that momentum is still there. "How's the new approach working? What's going well? What's challenging?"

This conversation is different in tone. You're supporting someone trying to improve, not addressing a problem. Ask what they need from you. Your job now is to help them succeed.

If things have improved, acknowledge it. "I've noticed you've hit the last two deadlines. That's exactly what we need." Positive feedback reinforces that the change matters.

If things haven't improved, address it directly but kindly. "I notice the approach we discussed isn't working yet. Let's troubleshoot. What's getting in the way?"

Document the follow-up conversation briefly. Not to build a case, but to keep a record of your support and their progress.

Handling difficult conversations at work is a learned skill that improves with practice. The framework, preparation, clear communication, listening, and follow-up, works across every type of difficult conversation: performance issues, interpersonal conflict, missed expectations, or changing priorities.

MacMillan Training Partnership works with managers and teams across the UK to build confidence in these conversations through practical, hands-on training. When your team can handle difficult conversations well, problems get solved faster, relationships stay strong, and people feel heard.
