Texas confirms employer's liability coverage is only available if the injured worker is an employee of the named insured

From Lexology, Anna M. Perry discusses a case which focused on workers compensaton insurance coverage and the language in the policy, but also discussed when a contractor may be a temporary employer of a temporary employee for the purposes of workers compensation. Anna writes:

A contractor may be deemed the temporary employer of a temporary employee under the borrowed employee doctrine if the temporary employer exhibits control over the temporary employee.² Generally, there are three factors to determine if the temporary employee is an employee of the temporary employer and therefore responsible for providing workers’ compensation insurance:
Did the temporary employee and temporary employer enter into a contract of hire, either express or implied?
Was the temporary employee’s work essential to that of the employer?
Did the temporary employer have control over the temporary employee’s work?
