A Foreign Domestic Worker (FDW) is expected to comply with Singapore's rules and regulations. The Government takes a serious view of FDWs who break the law or misbehave themselves.
You should call the Police immediately if your FDW physically abuses your family members or is suspected of committing a criminal offence e.g. theft. The FDW involved will be dealt with in accordance with Singapore's laws. Any FDW convicted will be banned permanently from working in Singapore.
You can provide feedback on FDWs via:
Domestic Permit Section
Work Pass Division
Ministry of Manpower
18 Havelock Road
Singapore 059764
The Work Pass Division will review the feedback you provide and place the FDW on records accordingly. This will be taken into account for the FDW's future Work Permit applications. However, the Ministry will not take action against the FDW for complaints on poor work performance.
