> I think the challenge will be for the employee to try and show that workplace conditions vs, WFH are so much worse to warrant organizing mass subordination as a way to improve it.
No, it won't be/ First, because its the NLRB that needs to make its case, but more significantly because the legal protection against retaliation for workplace organizing doesn't depend at all on a determination as to whether the organizing was "warranted" by how bad the situation was:
29 USC Sec. 157: "Employees shall have the right to self-organization, to form, join, or assist labor organizations, to bargain collectively through representatives of their own choosing, and to engage in other concerted activities for the purpose of collective bargaining or other mutual aid or protection, and shall also have the right to refrain from any or all of such activities except to the extent that such right may be affected by an agreement requiring membership in a labor organization as a condition of employment as authorized in section 158(a)(3) of this title."
29 USC Sec. 158(a): "It shall be an unfair labor practice for an employer-
(1) to interfere with, restrain, or coerce employees in the exercise of the rights guaranteed in section 157 of this title;"
