Yes? Was this disputed?

> If workers want to use their power to pressure companies, so should companies be able to do the same.

Why is that?

> On the contrary, it would simply put both companies and workers on the same standard.

If by “same standard” you mean equal footing, then I don’t see how you’d square that circle.

By definition an employer-employee relationship is asymmetrical, so is landlord-tenant, corporations-consumer, doctor-patient, teacher-student, etc.

In all those relationships one has more leverage than the other. Which is why, in most developed nations, there are guardrails in an effort to equalize that relationship.
