A Key Employee Leaves? Here’s What to Do

A key employee left? Here’s how to manage the transition smoothly, communicate well, and protect both client relationships and internal operations.

At some point, every business faces the same moment: a key employee decides to move on.

Sometimes they own important client relationships. Sometimes they hold an internal role that nobody else fully understands. Either way, how you handle the transition will determine whether it becomes a stressful disruption—or a smooth operational handover.

Here’s a practical, proven approach we use with service businesses to manage these situations with confidence.

Start With One Question: Who actually owns the client relationships?

When a client-facing employee leaves, the first step is to understand the nature of their relationships.

There are generally three scenarios:

1. The employee owns the relationship

The client trusts them. This creates retention risk the moment they leave.

2. The company owns the relationship

The client is connected to your brand, your processes, and your overall experience. Individuals matter, but no single person is irreplaceable.

3. You have a hybrid model

The employee is the main contact, but the company is still present—through shared inboxes, involvement from leadership, or a structured delivery process.

Classify each client into one of these categories. It’s the fastest way to understand where you need to step in early.

Build a Clear Transition Plan

Before you communicate anything, clarify what exactly needs to happen.

Role Audit

  • What responsibilities did this person have?
  • What’s currently in motion?
  • What deadlines or commitments need attention?

Capture Knowledge

  • SOPs
  • Project context
  • Client preferences and sensitivities
  • Open decisions or tasks

This prevents surprises once the person is gone.

Assign Interim Ownership

  • Who will take over for the next weeks?
  • And who will own this role long term?

Document this before you make any announcements. Most of the stress around employee departures comes from unclear ownership—not the departure itself.

Communicate Quickly and Thoughtfully

You don’t need a dramatic announcement. You just need clarity and timing.

Internal Communication (within 24–48 hours)

Make sure the team understands:

  • What’s happening
  • What the transition plan looks like
  • What will stay the same

Your tone sets the tone for everyone else—calm, straightforward, and forward-looking.

Client Communication

Clients should hear the news from you, not by noticing someone’s email bouncing.

Whenever possible, communicate via video message or live call. It’s more personal and gives clients confidence.

Keep it simple:

  • Share the change
  • Explain how continuity is ensured
  • Introduce the new point of contact
  • Give them the next clear step

The message should reassure clients that their work is not at risk.

Set a Transition Timeline

A timeline prevents confusion and helps everyone stay aligned. Include:

  • Date of internal announcement
  • Date of client communication
  • Handover meetings
  • Joint client calls
  • Knowledge transfer window
  • Final day and access removal
  • Internal wrap-up review

Even a simple timeline makes the transition feel organized and intentional.

Execute the Transition

Now it’s about following through. Either you do it or your COO.

Handover Meetings

Keep them structured so nothing falls through the cracks:

  • Current status
  • What’s expected next
  • Any risks or sensitivities
  • Who owns each upcoming milestone

Support High-Risk Clients

For accounts that relied heavily on the departing employee, schedule more check-ins during the first month. Clients should experience continuity, not turbulence.

Secure Your Systems

On the employee’s last day, remove access promptly. This is standard practice—not a sign of mistrust.

  • Remove logins
  • Change shared passwords
  • Check shared drives
  • Review API keys and integrations
  • Redirect email
  • Update client-facing tools (Calendly, CRM, support inboxes)

Clean access management keeps your business and your clients protected. Note. Depending on the context of the employee leaving, there can be cases where you want to revoke access immediately after learning about the departure, e.g. when trade secrets or client data is at risk.

Turning a Departure Into an Advantage

A key employee leaving can feel disruptive, but it’s also an opportunity. These moments reveal where your operations rely too heavily on individuals instead of systems.

Whatever caused friction during this transition should guide what you improve next.

If you realized one person held most client relationships, you might:

  • Join more client calls yourself
  • Add senior team touchpoints
  • Establish quarterly relationship check-ins
  • Make your delivery more system-driven

If you discovered undocumented processes, write them down.

If knowledge wasn’t shared, fix the structure.

If communication felt rushed, create templates for next time.

Over time, this turns employee departures from stressful events into smooth, predictable transitions.

And that’s the real goal: a company that stays stable when people come and go.
