How to run an employee engagement survey after an acquisition

Why survey employees after an acquisition?

An acquisition changes the answer to almost every question people ask about their job, often before anyone has the answers. A survey is the fastest way to hear from everyone at once, anonymously, about what they still need to know. For the wider picture of how deals affect people, see the impact of mergers and acquisitions on employees.

• Uncertainty is the main risk

  People in an acquired company want to know what changes for their role, their manager and their pay. Until they hear, rumor fills the gap. A survey shows which questions are still open, and where.

• The people you most want to keep can leave first

  Strong performers have options. Asking how people feel about staying, and acting on what they say, is cheaper than replacing them.

• Leadership needs a baseline

  Integration plans make promises about culture and retention. A baseline in the first months is the only way to show later whether those promises held.

• The group needs one view

  Once the acquired company sits in the same survey as the rest of the group, its results can be read against everyone else's, with the same questions and the same scale.

It is a common enterprise question. Acquisitions came up on 13% of the roughly 250 enterprise demo calls we analysed (organizations of 1,000 or more employees), twice as often as with smaller companies, usually as "how do we bring the companies we buy into the same survey?"

That tension, shared values across the group and room for each company to stay itself, is what the survey design below is built to measure.

When should you survey an acquired company?

Timing matters more than usual. Too early and people have nothing to react to; too late and the people with the most options have already decided.

The day-30 pulse is short on purpose. A pulse survey of five to eight questions shows where uncertainty is concentrated without asking people to commit to a view of a company they have only just joined.

Before close, the work is on your own side. Managers who will lead acquired teams, or whose teams will absorb them, are often new to it.

Who should take the survey after an acquisition?

The audience changes as the integration moves from the deal to business as usual.

• Only the acquired company

  For the first pulse and the baseline. The questions are about the deal, and the rest of the group would find them odd.

• The acquired company and the team that absorbs it

  When the acquired company is merging into an existing business, survey both. The receiving team's experience of the integration matters as much.

• The whole group

  From the next regular cycle. The acquired company answers the same core questions as everyone else, which is what makes comparison possible.

What to decide before the acquired company joins the survey

Five decisions make the acquired company's results readable on their own and comparable with everyone else's. Make them before the first invitation, because answers keep the groupings people had when they gave them.

• Report it as its own company. Set it up as its own business group, so it reads alone and inside the group total. Setup: business groups.
• Keep its people traceable after they move. Tag everyone who joined through the deal, for example a "Joined through" attribute, so the cohort stays visible after transfers. Setup: custom attributes.
• Decide who sees its results. Its own HR sees its people; group HR sees everyone; comments can be scoped separately from scores. Setup: sub-admin data scope.
• Decide where its employee data comes from. It can stay on its own HR system for now, or send a file, while the rest of the group syncs from yours. If either HR system changes later, stable employee IDs keep the trend intact. Setup: connecting an HRIS.
• Reach people in their language and at their local time. Translate the survey, and where enabled for your account, launch at the same local time in each time zone. Setup: survey languages.

For what the acquired company's employee data needs to contain, and how to clean it, see HRIS data for an employee engagement survey. For how several companies share one survey with separate access, see multi-entity employee surveys.

What questions should you ask after an acquisition? 24 to start with

Use these as statements on an agreement scale, alongside your standard engagement questions. Pick two or three per theme for the 30-day pulse, and most of them for the baseline.

Clarity

• I understand why the acquisition happened.
• I know what the acquisition means for my role.
• I know who to go to with questions about the changes.
• Leaders have told us what will change and what will stay the same.

Trust in leadership

• I trust the new leadership to make good decisions about our business.
• Leaders have been honest about what they do not know yet.
• Leaders have done what they said they would since the acquisition.
• My concerns are heard by people who can act on them.

My role and team

• I feel secure in my role.
• My manager keeps me informed about changes that affect our team.
• I still have what I need to do my job well.
• I can see a future for my career in the combined company.

Culture

• The things I valued about working here are being respected.
• I feel welcome as part of the wider group.
• I understand how the combined company expects us to work.
• People from both companies are treated fairly.

Ways of working

• Changes to systems and processes have been explained well.
• I have had the training I need on new tools.
• Working with colleagues from the acquiring company is getting easier.
• Decisions that affect my work are made at the right speed.

Intent and advocacy

• I see myself working here a year from now.
• I would recommend this company as a place to work.
• I feel positive about the combined company's future.
• What one thing would most improve how the integration is going for you? (open text)

Keep the deal-specific questions to the acquired company and the teams absorbing it. Everyone else keeps the standard group survey.

How do you keep a small acquired team anonymous?

Acquired companies are often small next to the group, and their people are the most worried about being identified. Anonymity has to be designed in, not promised.

• Results open only for groups at or above the anonymity threshold, 5 by default and never below 3. Below it, scores stay hidden. Setup: anonymity thresholds.
• Report a small acquired company as one unit at first. Cut by team or location only where each group clears the threshold.
• Avoid narrow combinations such as location by tenure by role, which shrink groups quickly.
• Say in the invitation who will see results and how small groups are protected. That sentence does more for participation than any reminder.

Should an acquired company score the same as the group?

An acquired company that scores below the group is not automatically a problem. On CultureMonkey's benchmark, engagement differs by company size, from 7.70 for companies under 100 employees to 8.16 for companies of 2,000 or more employees, and by region, from 7.67 in Europe to 8.22 in LATAM. Read a small or foreign acquisition against its own size band and region first, and against the group second.

Which engagement drivers drop first after a deal

Three drivers carry most of what changes in a deal: whether information flows, whether leaders are trusted, and whether people can see a future. On the benchmark they rank 16, 14 and 18 of 22, all below the median driver, before any acquisition has happened. Expect them to dip first and recover last.

How should you read the acquired company's results?

Five views answer the questions leadership will ask about the integration.

• Against the group

  The acquired company's score next to the group average and the other companies, on the same questions and scale. A gap is expected early; what matters is whether it narrows.

• Against its own baseline

  Each cycle compared with the day-60 baseline. This is the measure that tells leadership whether the integration is working.

• Inside the acquired company

  By team, location and manager, above the anonymity threshold. Integration rarely lands evenly; one site or function often carries most of the concern.

• By cohort, after people move

  The "Joined through" attribute keeps the cohort readable after people transfer into other teams, so you can see whether acquired employees settle in.

• In the comments

  Open-text answers grouped by theme show what the scores cannot: which decisions people are waiting for, and which changes landed badly.

Each survey keeps the hierarchy it launched with, so restructuring the acquired company after the baseline never moves the baseline's results. See how results by reporting line work.

How do you measure whether the integration is working?

Integration plans promise retention and a shared culture. These seven measures, read against the baseline every cycle, show whether the promise is holding.

What should you do with the results?

An acquired company watches closely what happens after it speaks up.

• Share results quickly

  Within two to three weeks, tell the acquired company what you heard, including the uncomfortable parts. Silence after a survey confirms the fear that nobody is listening.

• Answer the open questions

  Most early results point to things people do not know yet. Answering them, even with "we have not decided, and we will tell you by", is often the biggest single improvement.

• Give managers their own results

  Managers in the acquired company are fielding the questions. Their team's results, above the anonymity threshold, tell them what to address.

• Commit to two or three actions

  Choose a few changes, name owners and dates, and report progress at the next survey. See closing the employee feedback loop.

For the mechanics of reporting back and following through, see closing the employee feedback loop.

What should the survey invitation say?

The invitation is the first thing people read, and in an acquired company it is read for what it does not say. Keep it short, name who will see what, and promise a date for the results.

Send it from a leader the acquired company already knows, not only from the group. For a longer launch plan, see the enterprise survey rollout plan.

How do you make the case for the survey to your CHRO?

Leadership approves an acquisition survey for the same reason it approved the deal: the value sits in the people. Three points usually carry the case.

• The cost of losing people: put a number on regretted exits with the employee turnover cost calculator, then compare it with the cost of a survey programme.
• Evidence for the integration plan: a baseline and two follow-ups show the board whether retention and culture commitments are being met, in the same reports as the rest of the group.
• One view across every deal: each acquisition reads alone and against the group, and the data flows to Power BI or your warehouse alongside finance and HR metrics.

Common mistakes when surveying an acquired company

• Surveying in the first week

  Before anything has been announced, people have nothing to react to except rumor. A short pulse at 30 days and a baseline at 60 to 90 tell you more.

• Skipping the baseline

  Without an early measurement, there is no way to show later whether engagement fell, recovered or never moved.

• Merging the company into existing teams too soon

  Once acquired employees are spread across the acquirer's teams with no cohort marker, their experience disappears into the averages.

• Asking about the deal in the whole-group survey

  Questions about "the acquisition" confuse people who were not acquired. Keep integration questions to the acquired company and the receiving teams.

• Promising anonymity you cannot keep

  A 12-person acquired team cut by location and tenure exposes people. Keep cuts above the threshold and say so in the invitation.

• Dropping their old survey history

  Their previous vendor's reports are still useful. Keep them, repeat the questions you can, and read the trend side by side.

If the acquired company used a different survey vendor, see how to switch employee engagement survey vendors for keeping comparisons across the change.
