The IOU has the official seal, although it has the signature of the company personnel, but it should be regarded as the company's debt, which has nothing to do with the individual.

The act of writing IOUs by individuals belongs to the act of performing work tasks, which does not mean that individuals should bear the repayment obligation, and the company should bear the repayment responsibility. When a company goes bankrupt, as a creditor, it can apply for creditor's rights and safeguard its own rights and interests.
