Where I come from, what they are doing constitutes as workplace bullying and a lack in the employers responsibility of a duty of care for its employees. As an employee, you have rights, and as the employer, they have responsibilities.
Perhaps in your state too, it is a criminal offence, and if you are to suffer any mental instabilities as a result of your experience there I would recommend, seeking legal advice.
Often these actions by your employer can carry swift and harsh penalties, and leave you with compensation.
