If you were injured at your workplace, there are several factors that could impact the strength of your personal injury case:

1. Workers' compensation: In Texas, most employees are covered by workers' compensation insurance, which provides benefits for work-related injuries or illnesses. If you were injured at work, you should first file a claim for workers' compensation benefits. However, it's important to keep in mind that workers' compensation benefits may be limited, and they may not fully compensate you for your losses.

2. Negligence: If your injury was caused by the negligence of someone other than your employer, such as a third-party contractor, you may have a personal injury case outside of the workers' compensation system.

3. Injuries: The severity of your injuries will play a role in the value of your personal injury case. If you've suffered significant harm, you're likely to have a stronger case.

4. Evidence: Gathering evidence can be critical to the success of your personal injury case. This might include photographs of the accident scene, eyewitness statements, and medical records documenting your injuries.

5. Statute of limitations: In Texas, you generally have two years from the date of the injury to file a personal injury lawsuit.

It's also important to keep in mind that personal injury cases can be complex and often require the assistance of a knowledgeable attorney. An attorney can help you understand your legal rights and options, and can represent you in negotiations with the insurance company or in court, if necessary.
