I missed the part on your previous reply about having a union rep on the board. This is foreign to me as a US citizen so perhaps my vision is blinkered by the horrible state and history of labor relations here.

In a US context, with none of these kinds of arrangements in force, I do not accept arguments against much anything restricting worker's rights to organize here as there is so little alternative and even after organizing, true collective bargaining can be thwarted almost indefinitely (look at Amazon warehouse union efforts for examples of post-formation stonewalling).

In the German case or wherever there is a seat at the table for unions, a discussion can indeed be had. Here, I have zero sympathy for management which holds all the cards most of the time. Wikipedia in particular engaged a notorious anti-labor lawfirm to help their noble effort so I do not trust them in any way.
