I hope this message finds you well, present circumstances excluded. I am a licensed attorney with over a decade of employment law experience. It is a pleasure to assist you today.
First and foremost, in the state employment sector, it is important to be very familiar with your state employee handbook and the rights afforded therein. If you feel aggrieved, you should file a grievance based on what is taking place. If they do attempt to terminate you, then you will have an appeals process that you can start as well.
In short, aside from filing a legitimate grievance, there is not much you can do other than document things to use in your appeal later.
With that being the case, there are other outside things you can do under certain circumstances. If you feel this treatment is based on your age, gender, race or disability (if applicable), then you should set up a meeting with the EEOC and file an EEOC complaint. The EEOC will take a look at things and if they find merit, will allow you to sue for damages in federal court. Your employment will be protected as a part of this as well.
Let me know if you have any other questions or comments.
