How to Manage an Employee Who Isn't Improving

You have had the quiet word. Maybe more than once. Nothing has changed, and now you are stuck, absorbing work that is hurting the business, or edging towards letting someone go with nothing written down to support it. Managing performance fairly is not complicated, but it does need to be done properly. Here is how.

Be specific about what 'good' looks like

Most underperformance drifts because expectations were never made concrete. 'Not pulling their weight' is a feeling, not a standard. You cannot fairly manage someone against a target you never set.

Spell out exactly what good performance looks like in their role, where they are falling short, and what needs to change. In writing. That clarity is fair to them, and it protects you.

First move

Put the specific gaps in writing: what the standard is, and where they are not meeting it.

Support improvement, then review honestly

A fair approach gives the person a genuine chance to improve: clear objectives, a reasonable timeframe, and any support or training that would help. This is often a structured performance improvement plan.

Then you review honestly. If they have turned it around, brilliant. If they have not, you have a fair, documented basis for the next step, rather than a rushed decision you cannot back up.

First move

Set clear objectives with a realistic timeframe, and diarise the review now.

Is it capability, or is it conduct?

There is a difference between someone who cannot do the job despite trying (capability) and someone who will not (conduct). They are handled differently, and treating one as the other is a common, costly mistake.

Get this distinction right early and the right process follows naturally. Get it wrong and you can end up running the wrong procedure entirely.

First move

Work out whether you are dealing with capability or conduct before you choose a process.
