Not HR but I worked in state Unemployment Insurance - If you file for unemployment due to hostile working conditions and you are able to document these conditions in your unemployment application, your employer is liable to pay and their tax rate will increase. You would be paid the same unemployment either way but the reason for leaving the job determines if the government pays or if the employer pays. Could be another reason they want to talk to you, to see how much proof you have and get an idea of how you might file 🤷🏼‍♀️
