Workers' Compensation for Part‑Time Employees at Costco in New Jersey

Eligibility and Coverage Basics

In New Jersey, all employers, including Costco, must carry workers' compensation insurance regardless of the employee's hours. Part‑time workers—those who work fewer than 20 hours per week—are entitled to the same benefits as full‑time staff if they suffer an on‑the‑job injury or illness. The key eligibility factor is the injury's connection to the employee's job duties, not the number of hours worked.

Determining the Injury's Work‑Related Status

To qualify, the injury must arise out of, or occur in the course of, the employee's work. Examples include:

• Repetitive strain from lifting boxes in a warehouse.
• Slips or falls while stocking shelves.
• Exposure to hazardous materials during cleaning duties.

Part‑time employees who are injured while on a Costco shift, or during a paid travel or training session, will typically be covered. Injuries occurring outside working hours, such as a car accident on a personal trip, do not qualify.

The Claim Process for Part‑Time Workers

1. Report the injury to the supervisor or HR within 48 hours. Provide a written statement if possible.

2. Obtain a medical evaluation from a certified provider. Costco may designate an in‑network physician or allow the employee to choose their own.

3. Complete the NJ Workers' Compensation Claim Form (Form W-4) and submit it to the employer's insurance carrier. The carrier will review the claim and issue a decision.

4. If approved, the employee receives wage replacement and medical benefits. If denied, the employee can appeal within 30 days of the denial notice.

Employer Responsibilities and Record‑Keeping

Costco must maintain accurate payroll records showing each part‑time employee's hours and wages. These records are crucial for determining benefit amounts, as wage replacement is typically 2/3 of the employee's average weekly wage. Employers must also submit payroll reports to the New Jersey Department of Labor and Workforce Development (NJDLWD) on a quarterly basis.

Failure to provide proper records can result in penalties and may jeopardize the validity of a claim. Employers are also required to keep medical records confidential and comply with the New Jersey Workers' Compensation Act's privacy provisions.

Common Challenges for Part‑Time Workers

1. Misunderstanding coverage limits: Part‑time workers often assume they are excluded, but the law treats them the same as full‑time staff.

2. Delayed medical treatment: Inconsistent work schedules can lead to gaps in care coordination.

3. Benefit calculation disputes: Because wage replacement is based on reported wages, inaccuracies in timekeeping can affect payouts.

Preventive Measures for Costco and Employees

Costco can reduce injury risk by:

• Providing ergonomic training for all staff, regardless of hours.
• Ensuring proper signage and floor markings in high‑traffic areas.
• Offering regular safety briefings that include part‑time workers.

Employees should:

• Report any unsafe conditions immediately.
• Follow all safety protocols, even during short shifts.
• Keep a personal injury log to aid documentation.

Appealing a Denied Claim

If a part‑time Costco worker's claim is denied, the first step is to file an appeal with the NJ Workers' Compensation Commission within 30 days. The appeal process involves submitting additional medical evidence and a written statement. If the appeal fails, the employee may file a lawsuit in a New Jersey Superior Court, though this is typically a last resort due to higher costs and longer timelines.

Key Takeaway

Part‑time employees at Costco in New Jersey are fully protected under state workers' compensation laws. By promptly reporting injuries, maintaining accurate records, and following established procedures, both employer and employee can ensure a fair and efficient claims process.
