Was it on her personal Facebook page?
Was that facebook page an official outlet of her employer? Was she the official spkesperson for her employer, or using her facebook page in a capacity related to the business?
If all those are answered with “No”, whats the problem?
I think the only people that crossed a line was her employer. Screwed up US employment law clearly hasn’t helped either.
I sincerely hope Akima LLC lose more business than her salary over this
