As a freelancer, you can work for either one or more work providers at the same time without a permanent employment relationship.
As a freelancer, you act as either an employee or an entrepreneur, or you are paid non-wage compensation for your work. You can enter into a service agreement, which creates a fixed-term employment relationship, or you perform the work as an entrepreneur. If you receive non-wage compensation for your work, labour law will not apply to you, but your status is considered comparable to that of an entrepreneur.
Many people become freelancers because this provides them with more freedom to influence their own working methods, working hours and content of projects. However, as a freelancer, you have more responsibility for your livelihood and the fulfilment of your rights than employees.
In some industries, freelancing is such a well-established way of finding employment that there may be hardly any other options available.
