What Does 49 CFR 40.303 Require?

40.303 addresses continuing services after Return to Duty: the SAP's recommendation, the employer's option to require it, and your obligation to comply.Part 40 Regulatory Reference

Short Answer

49 CFR § 40.303 addresses what happens when the Substance Abuse Professional (SAP) believes an employee needs continuing services, such as aftercare or support group participation, after the employee returns to safety sensitive duty. The SAP includes these recommendations in the follow up evaluation report. The employer may require participation in those services as part of a return to duty agreement and may monitor compliance, but doing so does not replace the employer's separate follow up testing obligation. The employee is obligated to comply with the SAP's recommendations for continuing services, and failure to do so may lead to employer discipline.

Detailed Explanation

Paragraph (a): The SAP Documents the Recommendation

When the SAP believes ongoing services are appropriate after Return to Duty, whether that means continued outpatient counseling, a support group, or another form of aftercare, the SAP includes that recommendation in the follow up evaluation report sent to the Designated Employer Representative (DER). This recommendation is one of the specific items required in the follow up report content described in 40.311(d)(10).

Paragraph (b): The Employer's Option to Require and Monitor Compliance

An employer may, as part of a return to duty agreement, require the employee to participate in the recommended continuing services and may monitor and document that compliance, including through an Employee Assistance Program (EAP). This is an option available to the employer, not a substitute for the employer's separate obligation to carry out the SAP's follow up testing plan under 40.309. Follow up testing and continuing care monitoring serve different purposes and both remain in place.

Paragraph (c): The Employee's Obligation

The employee is obligated to comply with the SAP's recommendations for continuing services. If the employee fails to do so, that failure may lead to discipline by the employer. This places a real, ongoing responsibility on the employee that extends beyond the follow up evaluation itself and into the period after Return to Duty.

Applicable Regulations

49 CFR § 40.303 addresses recommendations for continuing services after Return to Duty, the employer's option to require and monitor compliance, and the employee's obligation to comply with those recommendations.

Professional Observation

In my experience, employees sometimes assume that once they pass the Return to Duty test, the process is essentially finished. Section 40.303 is a reminder that the SAP's continuing care recommendations, and the employer's follow up testing obligation, both continue well beyond that first negative test. Treating aftercare recommendations as optional after returning to work is one issue I often see create avoidable problems later.

Common Misconceptions

Misconception

If the employer requires participation in aftercare or support groups, follow up testing is no longer necessary.

Reality

Section 40.303 specifically states that monitoring continuing services does not replace the employer's follow up testing obligation under 40.309. Both requirements operate independently and at the same time.

Why the Confusion Occurs

Because both continuing care monitoring and follow up testing are ways of confirming an employee's ongoing recovery, it is easy to assume one can substitute for the other. The regulation treats them as separate, complementary requirements.

Frequently Asked Questions

Is the employer required to offer an Employee Assistance Program to monitor continuing care?

No. The regulation allows the employer to monitor and document compliance, including through an EAP, but it does not require the employer to have or provide one. Whether an EAP is available depends on the employer's own policies and benefits.

What happens if an employee stops attending recommended aftercare after returning to duty?

The employee is obligated to comply with the SAP's continuing service recommendations, and failing to do so may lead to employer discipline. The specific consequences depend on the employer's policies and the return to duty agreement in place.
