Get a lawyer. It's a legal fight and you need a trained professional to stand with you and fight for you. You will be treated more seriously if you have legal representation. If there are privacy laws where you live, decline answering when they ask if you are vaxxed or getting vaxxed. (i,e/ "I only discuss my personal confidential medical information with my doctor.") Dont sign their forms or fill out their questionnaires. Keep returning to work. Do your job. Make them remove you or send you home, then release your lawyer on them. Where I live, wrongful dismissal cost the employer 2yrs salary in damages. Don't walk away without fighting.
