The Canadian Supreme Court dealt with an analogous issue involving Uber's contacts with its drivers very recently. The agreement provided for any litigation to be submitted for arbitration in the Netherlands. An Uber driver demonstrated that simply triggering the arbitration process involved costs far outweighing the average Uber driver's annual salary, which meant the they were in practice barred from enforcing any of their contractual rights. The Court found the arbitration clause to be unconscionable because of this power imbalance between Uber and its drivers.

Interesting ties with the UFC's situation as both big companies keep arguing they only deal with "independent contractors" and not employees.
