Communication: First, try to communicate with the person in charge of the delinquent fee or the person involved, ask about the reason for the delinquency, and try to come to a clear repayment plan.
Preserve evidence: Make sure to keep all work-related documents and evidence, including contracts, invoices, work records, etc. These documents will help prove your workload and the remuneration you deserve.
Seek legal assistance: If communication fails, you may consider seeking legal assistance. Consult with a lawyer or legal aid agency to understand your rights and legal options.
File a lawsuit: If necessary, you may consider filing a lawsuit in court. Before doing so, make sure you have a good understanding of the legal process and have all relevant evidence ready.
Seek third-party mediation: You can also try to seek third-party mediation, such as a trade association or mediation center. These agencies may be able to help you reach a settlement with the party who is in arrears.
Whatever you do, you need to make sure that your rights and interests are protected and that you avoid taking drastic actions as much as possible. It is very important to remain calm and rational when dealing with such issues.
