Answer:
HR policies and employment agreements about IP may or may not be enforceable, depending on current law and location.
Step-by-step explanation:
HR is in charge of creating policies that will help protect the company from employees or former employees from sharing sensitive information of the company. However, the legal system tends to rule in favor of the employees in cases related to these policies and sometimes, it limit the use of them. For example, in the case of former employees that signed a non-compete agreement in which they are not allowed to work for a competitor, the court may favour that person because the right to have a job to be able to make a living is more important. According to this, the answer is that the challenge concerning policies about IP is that HR policies and employment agreements about IP may or may not be enforceable, depending on current law and location.
