If you do have any protection, it will come from state law. Federal laws and the majority of state laws only provide whistle-blower protection to those who report their employers to authorities or government offices for violations of existing laws. These are not company policy or company rule violations, but violations of actual laws that are reported to the enforcing agency.
For example, in a trucking firm if a truck driver reports an ineffective truck repair that causes violations of the state laws to the Department of Transportation in that state, that truck driver is a whistle-blower. On the other hand, if the truck driver merely reports the problem to the vice president of truck maintenance, that does not qualify for whistle-blower protection under the law.
Be careful with reporting your supervisor to the human resources department constantly. Your employer may consider these multiple reports regarding your supervisor to be a negative mark on you instead of on your supervisor. For some employers, constantly complaining about your supervisor is an indication of a problem with your attitude or that you do not have enough work to keep you busy. While it is great to be cognizant of the company rules, unless you have been appointed as the company police, your reporting of others may show that you are not a team player.
