Open enrollment is often treated as an annual administrative task—but in reality, it is one of the most important opportunities an employer has to engage employees, communicate value, and reinforce trust.

Done well, it strengthens your benefits strategy and employee satisfaction. Done poorly, it creates confusion, frustration, and underutilization of your benefits investment.

Below are the five most common mistakes employers make during open enrollment—and how to avoid them.

Mistake #1: Starting Too Late

Many employers underestimate the amount of planning required for a successful open enrollment.

Waiting until the last minute leads to:

• Rushed communication
• Limited employee understanding
• Missed opportunities to educate and engage

What to do instead:
Start planning at least 60–90 days in advance. This allows time to:

• Finalize plan decisions
• Develop communication materials
• Coordinate with carriers and vendors

Mistake #2: Focusing Only on Plan Changes

Employers often focus heavily on what’s changing—rates, deductibles, or carriers—but fail to clearly communicate the overall value of the benefits program.

Employees don’t just want to know what changed—they want to understand:

• What they have
• How it works
• Why it matters

What to do instead:
Frame your messaging around:

• Total benefits value
• Financial protection
• How the plan supports employees and their families

Mistake #3: Overcomplicating the Message

Benefits can be complex, but communication shouldn’t be.

Too much information—or overly technical explanations—can overwhelm employees and lead to poor decision-making.

What to do instead:
Keep messaging simple and focused:

• Use clear, plain language
• Highlight key decisions employees need to make
• Provide examples of how benefits work in real-life scenarios

Mistake #4: Ignoring Voluntary Benefits

Voluntary benefits are often presented as an afterthought, with little explanation or context.

As a result:

• Participation is low
• Employees don’t understand their value
• Employers miss an opportunity to enhance their overall benefits strategy

What to do instead:
Position voluntary benefits as:

“Protection for what your medical plan doesn’t cover.”

Focus on:

• Accident, critical illness, and hospital indemnity
• Income protection through disability
• Supplemental life coverage

When properly communicated, these benefits can significantly improve employee financial security.

Mistake #5: Lack of Employee Engagement and Support

Simply sending out emails or hosting one meeting is not enough.

Employees need:

• Time to understand their options
• Access to guidance
• Confidence in their decisions

Without this, employers often see:

• Low participation
• Poor plan selection
• Increased confusion and HR follow-up

What to do instead:
Create a structured engagement strategy that includes:

• Multiple communication touchpoints
• Educational materials and decision guides
• Access to enrollment support (live or virtual)

The Bigger Issue: Treating Open Enrollment as a Transaction

The underlying issue behind most of these mistakes is treating open enrollment as a one-time transaction instead of a strategic process.

Open enrollment should be viewed as:

• A communication strategy
• An education opportunity
• A key driver of employee satisfaction and retention

How a Strong Open Enrollment Strategy Creates Value

When done correctly, open enrollment can:

• Increase employee understanding and appreciation of benefits
• Improve participation in key programs
• Reduce confusion and administrative burden
• Strengthen trust between employer and workforce

It also ensures that your investment in benefits is actually delivering value.

Final Thoughts

Open enrollment is not just about selecting plans—it’s about helping employees make informed decisions that impact their health, finances, and overall well-being.

Employers who approach it strategically will see better outcomes across the board:

• Higher engagement
• Better plan utilization
• Stronger workforce satisfaction

Those who don’t will continue to face the same challenges year after year.

If you’re looking to improve your open enrollment process—or want to ensure your strategy is aligned with your overall benefits objectives—this is an area where the right approach can make a measurable difference.
