If something at work feels wrong, identify the problem before choosing the help route. Underpayment, unsafe work, discrimination, dismissal and a contract dispute may involve different organisations.

ProblemUseful route
Contract, dismissal, salary disputeUnion such as FNV/CNV, legal adviser or Juridisch Loket depending on eligibility/situation
Below statutory minimum wage / labour-law enforcement issueNetherlands Labour Authority (Nederlandse Arbeidsinspectie)
Unemployment / employee-insurance benefitUWV
DiscriminationLocal anti-discrimination service and/or Netherlands Institute for Human Rights depending on the issue

Keep evidence

Keep the contract, CAO, payslips, rosters/time records, relevant emails/messages and a dated record of important conversations. Ask for important decisions in writing. If you are underpaid, official government guidance recommends first raising it with the employer; if it is not corrected, the Labour Authority or legal action may be routes.
