We do agree that shareholders, who supposedly own the company in some sense, can definitely express their opinions freely, cajole or threaten the directors and officers of the company, and directly or indirectly "spike business deals", right? And if some activist investor(s) were threatened with having their stock taken away because they were causing trouble, that would not just happen, there would be instant legal warfare which the entrenched interests might well lose, right? Assuming everybody takes all that for granted, why would it be unreasonable for workers to have the right to do similar stuff without being fired? Especially if the damn law says they do.
