Hi there! Thank you for the opportunity to help you with your question!
One example of unethical behavior I have observed in my previous employment is copyright infringement among employees. At my place of work, I would notice that many of the employees would use pirated software, even passing it on to one another. This is hypocritical, since, as a company, you expect people to pay for your products, and there they were pirating software in order to save a few hundred dollars.
Please let me know if you need any clarification. Always glad to help!
