    Short answer: the difference between agency work and secondment lies in your contract. With agency work, your contract often ends when the work ends. With a secondment, you work at one company for a longer period. Job finished? Then you usually keep your contract.

    You're scrolling through job vacancies. One says agency work, another says secondment. Huh? Isn't that the same thing? No. But the difference is simple. Here's everything you need to know in just a few minutes.

    What is agency work? Working with the agency as your employer

    Imagine you work in a large warehouse at the port. But your contract isn’t with that warehouse. Your contract is with the employment agency. The agency is your employer and pays your wages. The warehouse tells you what to do. You often work at one place for a few weeks or months. Does the company no longer need you? Then your contract often ends too. Don’t panic: the agency will help you find new work. And you earn the same as permanent colleagues doing the same job. The rules are set out in the collective labour agreement for agency workers.

    What is secondment? One workplace for the long term, with security

    Imagine you’re a mechanic. You have a contract with a secondment agency. The agency places you with one company for a long period, a factory, for example. Not for a few weeks, but for months or even years.

    Is the work at the factory finished? Then you usually keep your contract and your wages. The agency finds a new placement for you. Secondment is especially common among skilled tradespeople, such as mechanics and carpenters.

    What is the difference between agency work and secondment?

    First, what’s the same. In both cases, the agency is your employer. And the company where you work tells you what to do. Here’s what’s different:
    1. The contract. With agency work, your contract can end when the work ends. With a secondment, it usually continues.
    2. The duration. Agency work is often shorter. With a secondment, you stay in the same place for a long time.
    3. The type of work. Agency work is possible in almost any kind of job. Secondment is mainly for skilled tradespeople.
    In short: agency work gives you freedom, secondment gives you security.
