It's like having prayer in school. It might seem like a good idea on its surface to some, but then you have to decide whose prayer. In Engel v. Vitale many religious groups actually filed amicus briefs against having public school start their day with a prayer because to be nearly universally acceptable, it had to be designed by a committee to be as bland and unobjectionable as possible.

Likewise, anything publicly debated at work has to be inherently bland and without class consciousness, as that calls into question relationship between the workers, the professional management classes and the reigning neoliberal order. The only approved topics will ones that distract from class consciousness and divide the workers into factions that render them unable to operate cohesively.
