Few things put business owners under pressure quite like a complaint from an important client.
Perhaps they’ve raised concerns about an employee’s behaviour, questioned their professionalism, or even asked for them to be removed from a project altogether.
When a valued client is unhappy, it’s natural to want to fix the situation quickly. But making decisions based solely on a client’s demands can create a much bigger problem.
As an employer, you have a responsibility to protect your business, your client relationships, and your employees’ rights. Striking the right balance is essential.
Don’t Rush to Conclusions
One of the biggest mistakes employers make is treating a complaint as proof that something has gone wrong.
At this stage, it’s simply an allegation.
While the client’s concerns should be taken seriously, your employee is entitled to explain their side of the story before any decisions are made.
Taking disciplinary action without carrying out a fair investigation can expose your business to unnecessary risk and potentially lead to costly legal disputes.
The key is to stay objective and focus on the facts.

Start by Acknowledging the Complaint
When a client raises a concern, respond promptly.
Thank them for bringing the matter to your attention, reassure them that you’re taking it seriously, and explain that you’ll investigate the issue.
What you shouldn’t do is promise a specific outcome.
Avoid committing to disciplinary action, apologising on behalf of the employee, or agreeing to remove them from a project before you’ve established what has actually happened.
Speak to Your Employee
Before making any decisions, arrange a private conversation with the employee involved.
Explain the concern that has been raised and give them the opportunity to share their perspective.
Keep the discussion calm and factual. The purpose at this stage is to gather information, not to conduct a disciplinary meeting.
Very often, there are details, misunderstandings, or circumstances that weren’t apparent from the initial complaint.
Carry Out a Proper Investigation
A fair investigation doesn’t need to be complicated, but it does need to be thorough.
Record:
- What the client has alleged
- When the issue occurred
- Any evidence or supporting information available
- The employee’s explanation
- Any relevant witness accounts
As you build a clearer picture, consider the wider context.
For example:
- Has a similar concern been raised before?
- Was there a misunderstanding or communication breakdown?
- Were there external pressures contributing to the situation?
- Is this genuinely a conduct issue, or does it highlight a training or process gap?
The answers will help determine the most appropriate next steps.
Choose the Right Outcome
Not every complaint should result in formal disciplinary action.
If your investigation confirms misconduct, you may need to follow your disciplinary procedure and deal with the issue formally.
However, some situations are better resolved through additional support, clearer expectations, further training, or changes to internal processes.
Equally, if the complaint is unfounded, it’s important to document your findings and record why no further action has been taken.
The goal is to reach an outcome that’s fair, reasonable, and based on evidence rather than emotion.
Keep the Client Informed
Once you’ve investigated the matter, don’t leave the client wondering what happened.
You don’t need to disclose confidential employment matters or share internal decisions. However, you should let them know their concerns have been reviewed and addressed appropriately.
Most clients don’t expect every detail. They simply want to know that they’ve been listened to and that their concerns have been taken seriously.
Clear communication can go a long way towards preserving trust and maintaining the relationship.
