This scenario describes a severe, multifaceted ethical violation and potential corporate espionage. Cost estimates, bidding strategies, and proprietary design details belong exclusively to the employer; they are highly confidential trade secrets. The friend is essentially offering a bribe (a job and a bonus) in exchange for stolen confidential information that would give the competitor an unfair advantage in the bidding process. Stealing this information violates the core ethical duty of fidelity and loyalty to the current employer. It is a direct breach of confidentiality. Furthermore, entertaining the offer while currently preparing a bid for the employer creates an immense, immediate conflict of interest. Therefore, this situation most directly relates to the ASET ethical principle mandating that members must "Act with integrity towards clients or employers, maintain confidentiality and avoid a conflict of interest." A professional technologist must immediately reject this unethical offer and ideally disclose the competitor's corrupt behavior to their current employer.
