Was this employee allowed by law to record us secretly?

Q: “I counseled an employee who had a confrontation with another manager. After the meeting with both of them, I was told that the employee recorded our entire meeting using her cellphone. I told her that if this was true, she should erase it, as she didn't have our permission to record us, and since patients’ names were mentioned, she is violating our confidentiality (HIPAA) policies. The employee filed for unemployment two days later claiming she was fired, but the decision to let her go was not made until a week later. Was it legal to record us without permission, and could she file for unemployment thinking she might be fired?” – Anonymous, Pennsylvania
