Credit union mergers are often advertised as financial wins, but culture alignment ultimately determines the value of unification.
Merger trends show a significant reduction in merging due to financial crisis. According to the NCUA, 76% of credit unions cited “expanded services” as the top reason for merging from 2017 to 2021 and looking at 2025 data in their Merger and Insurance Reports, 62% continue to use that as the main reason.
Credit unions are describing these “strategic” or “collaborative” merger gains with generic phrases like “gaining economies of scale” and “increased efficiencies.” Boards and executive leadership should specify how those benefits translate into actual experiences, starting with those who experience mergers first and absorb the biggest share of changes: employees.
The impact of a merger on employees
Employees carry some of the biggest burdens before, during, and after the merger. The initial announcement inevitably creates uncertainty about what changes will eventually come and what impact they will have.
What will the new mission, vision, and values be like, and what behaviors and expectations will determine success within the new culture? What do future career paths look like? How will daily processes and procedures change? Who are the new leaders, and who will help individuals grow through their careers? While mergers can boost the benefits in many areas, the biggest question is “How will leadership handle these changes?”
Culture starts with employees. Their values, perceptions, experiences, and behaviors ultimately determine the credit union’s brand, voice, and operations. If two credit unions are performing a collaborative merger, then arguably, their employees and cultures are two of the top driving factors that brought those organizations together.
To protect service expectations and cultural values that made the individual credit unions good, considering, planning, and carefully implementing the changes that will make the new organization great will be imperative.
Culture clashing creates employee turnover and confusion
Operationally, new merger-based procedures and policies have the potential to solve problems and enhance member experience but can create confusion and frustration as what was once acceptable may no longer be okay. Regulatory pressure can reduce the credit union’s risk appetite and elevate decision-making to high authorities. While this may save the credit union time and money in the long run, front-line employees lose their ability to learn how to make informed decisions.
Uncertainty about how to perform normal job functions, where employees fit in the new organizational structure, and losing their sense of belonging when combining “like” organizations can decrease morale and productivity.
PMI Stack’s article “50+ Post-Merger Integration Statistics: What the Data Really Says,” found 47% of employees voluntarily leave in the first year after a merger. The threat of becoming ineffective, moving to another department, or losing one’s job is a major indicator of turnover. Implementing predictability and transparency during the transformation can ensure cultural integration goes smoothly.
It’s hard to deny that mergers allow for investments small institutions simply cannot make. Technology is expensive. Having a bigger bottom line to invest in tech is something that is hard for some credit unions to pass up. Many small credit unions boast that their employees “wear multiple hats,” and a symptom of that problem comes with the inability for employees to focus and strengthen specific knowledge and skills.
Mergers can allow rock stars to elevate their expertise by giving needed support to share the daily task wealth. The problem is the majority of integrations fail due to the execution of the integration, according to the previously mentioned PMI Stack article, and they cite the biggest challenge as culture alignment.
Measuring merger success by employee engagement
If employee experience is so drastically changed during a merger and cultural alignment is the reason for “failure,” employee retention and engagement should be the top measurements of success. Credit unions can develop a Key Performance Indicator related to retention on their strategic plan.
By building and routinely reviewing trends before, during, and after the merger, turnover issues can be brought to light and addressed before they get out of hand. Recurring pre- and post-merger cultural surveys can provide valuable insight as to the realities of the culture the team is facing. Reviewing these results with the entire organization can guide the day-to-day initiatives to create an inclusive work environment rather than an isolating one.
Other culture measurement considerations include: How to measure the effectiveness of leaders coaching and developing employees? How successful is collaboration when employees from different brands pre-merger come together post-merger? What is the best way to track promotions given, their merit, and ensure a narrative that speaks to collaborative benefits rather than us vs them?
Combine with care
In the end, mergers combine products, technologies, and balance sheets. The employees determine if those integrations become a shared culture or two organizations working side-by-side without ever truly becoming one.
