Hi, I'd like to help you with your question.
I understand your concern. After reading your previous question and this one as well, it appears that your supervisor is finding her job a bit overwhelming. She sounds ill prepared to cope with your feelings about her conduct and she is taking your comments personally, instead of handling them as a manager. She may not be comfortable in her role and is unable to respond in a professional way so she bans you from making further comments. This is not a good way to deal with how you feel. She needs to be open to your comments and respond in a professional way. Also, she cannot treat you differently from any other employee, just because she does not like what you have to say.
Although you may no longer be able to go to her about how you feel regarding her work with you, she cannot ban you from communicating with the manager above her or with human resources, if things should become unfair or discriminatory. You have a right as an employee to file complaints and have them addressed, just as any other employee does. To be treated differently is discrimination.
However, at this point, you may want to let this situation go. Making this a big issue may reflect on you in a bad way because it becomes your word against hers. But what you can do is start making notes about what is going on. If this becomes a trend, you will have times, dates and a written account of your situation. This lets you be taken seriously if this becomes a bigger issue over time. Also, explore your rights as an employee. Your company should have a set of rules that you can familiarize yourself with so you know your rights and your boundaries. This will help you know how to approach this problem or any others that occur and who you can turn to for help.
I hope this helps,
