ABC Services, Inc. has a policy in its employee handbook that prohibits employees from criticizing the company or its managers. Billy Bigmouth, an employee of ABC with no employment contract, posts a negative review of ABC on Indeed.com, a job search website. In the review he says "This Company is totally f___ed up, and its CEO is a total d___head who must have flunked 3rd grade!" No other ABC employees post anything or comment on the post. ABC fires Billy for the post. Does he have a claim against the Company?
A-Yes, under the NLRB, because he was engaged in protected concerted activity when he made the post
B-Yes, because ABC is not allowed to infringe upon an employee's first amendment rights of free speech
C-No, because no other employees were involved in the posts, and therefore it was not protected concerted activity
D-No, because there are absolutely no limits to ABC's ability to fire Billy since he is an at-will employee
