What is the ruling of Islamic law regarding a company manager who knows about thefts and manipulations but takes no action, on the pretext of there being no alternative or the insignificance of the stolen amounts compared to the company's profits, and to what extent is he responsible for these thefts?

The manager is responsible for the company and its trust, and is obligated to pursue its interests. He will be questioned about his flock on the Day of Judgment. His negligence in not seeking out trustworthy and experienced individuals, and his silence regarding thefts, constitute a betrayal of trust. He must exert effort to prevent theft, otherwise, he shares in its sin. This matter becomes even more severe in public sector companies, as public funds are considered more sacred.
