If you find that a colleague has used company resources without authorization, even if no losses have been caused at present, it is recommended that you report this behavior to your superior. There are several reasons for doing this: 1. **Protect the interests of the company**: Although there is no loss now, this behavior may cause problems in the future, including financial losses or moral risks. 2. **Maintain company policies**: Unauthorized use of company resources usually violates company policies and regulations. Timely reporting helps maintain the seriousness of company rules and regulations. 3. **Prevent the incident from escalating**: If it is not handled in time, other colleagues may follow suit and cause bigger problems. 4. **Provide an opportunity for solutions**: After reporting to the superior, management may take action to clarify the relevant rules to prevent similar incidents from happening again. Of course, when reporting, you can try to be objective, describe the facts, and avoid making unnecessary accusations against colleagues, so as not to affect the team atmosphere.
