Helping someone cheat, whether it's a husband or anyone else, is generally considered unethical and unprofessional behavior for a social worker.
Social workers are bound by a code of ethics that emphasizes the importance of integrity, honesty, and respect for the well-being of their clients and the broader community. Encouraging or assisting someone to engage in deceitful or harmful behavior goes against these ethical principles.
If a social worker becomes aware of issues within a client's relationship, their role should be to promote open communication, provide support, and explore healthy resolutions to problems. Encouraging dishonesty or infidelity would not align with the values and responsibilities of a professional social worker.
If a social worker finds themselves in a situation where they feel conflicted or unsure how to proceed, they should consult with their supervisor, an ethics committee, or a trusted colleague for guidance. Upholding professional ethics is critical for maintaining trust and credibility in the field of social work.
