Perhaps you are looking for a job or want to start you own business?
If you are looking for a job you can visit one of the many temporary job agencies (“interimkantoren”) or consult the VDAB, the public employment service of the Flemish government, that also has one of the largest job sites in Belgium. Dutch is still the most common language used on the work floor. Depending on the job, other language skills (English and/or French, etc.) are often required.
As an employee, you can become a member of a trade union (“vakbond”) to defend your rights. The unions in Belgium are organised along politico-denominational lines, following the pillarisation in Belgian society. Therefore, the three major trade unions are all confederations, each adhering to a particular religion or ideology, namely Christian (Catholic), Socialist and Liberal.
If you want to start your own business, the city council can help you. You can also consult this website.
