Section 19 is designed to ensure that agency workers who are neither employees working under a contract of service nor self-employed under a contract for the provision of services are properly insurable. Agency employment has been recognised and addressed in other employment legislation to ensure that agency workers may avail of legislative protection. This section contains two amendments designed to clarify the position of agency workers under the social welfare code. The first amendment states that individuals employed through an employment agency are insurably employed and the second amendment indicates that the person who is liable to pay the wages or salary of the individual in respect of the work or service performed will be deemed to be the employer.
