When plan sponsors think about retirement plan risk, they often focus on dishonest employees, cybersecurity threats, or regulatory changes. In my experience, the most dangerous employee in a retirement plan is often none of those things. It is the employee who knows just enough about the plan to be dangerous.
Every organization has one. They attended a webinar a few years ago, read an article online, or had experience with a previous employer’s plan. They become convinced they understand the rules and begin making decisions based on assumptions rather than the actual plan document. Before long, they are overriding payroll procedures, making eligibility determinations, approving distributions, or interpreting plan provisions without consulting the TPA, recordkeeper, or ERISA counsel.
Retirement plan errors rarely occur because someone intended to violate the rules. Most operational failures result from well-meaning individuals trying to solve a problem on their own. An employee decides a worker should be excluded because they are “part-time.” Another assumes a rehired employee must wait another year for eligibility. Someone else believes a payroll issue can simply be fixed next pay period. These decisions can create costly correction programs, additional employer contributions, and unnecessary audit findings.
The solution is not to discourage employee involvement. The solution is to establish clear processes and ensure everyone understands their role. Retirement plans operate best when responsibilities are defined, decisions are documented, and questions are directed to qualified service providers before action is taken.
One of the most important lessons I have learned in more than twenty-five years practicing ERISA law is that expertise matters. Good intentions do not correct operational failures, and assumptions do not override plan terms.
The most dangerous employee in your retirement plan is not the one who knows nothing. It is the one who believes they know enough that they no longer need to ask questions.
