Question: Can I be fired for giving a 1 star review to the company I work for?

So at the time of hire, my employer did not disclose any information relating to their health insurance coverage. a month later I asked about it, they gave me the providers number and I missed the deadline by a few days. mind you I have a sick premature child who needs care. If they told me anything about insurance I would have remembered and acted immediately. The employer told me I ignored or discarded the info, but he would see if he can work around it. I never heard back. I gave them a 1 star review on google with no comment. He then blasted me about the 1 star over email after work hours. Legally can he do anything such as term me because of giving this 1 star rating?
