Employers use arbitration agreements to move disputes out of court and to limit collective actions. Enforceability turns less on the concept than on formation and fairness.
Formation. Did the employee actually agree? Agreements buried in a handbook the employer reserves the right to change unilaterally are vulnerable, because a promise that can be withdrawn at will may be illusory. Electronic acknowledgement records matter here more than the drafting.
Unconscionability. Courts examine both how the agreement was presented and what it says. Terms that recur as problems: costs imposed on the employee beyond what a court would charge; a shortened limitations period; a bar on remedies otherwise available; one-sidedness, where the employer may litigate and the employee may not; and control of the arbitrator selection.
Class and collective waivers are generally enforceable in employment agreements, which is often the employer’s principal objective.
Carve-outs. Some categories of claim are excluded from mandatory arbitration by statute, and nothing prevents an employee filing an administrative charge. Well-drafted agreements say so rather than appearing to prohibit it.
Practical points for employers: present it as a standalone document with separate acknowledgement, keep the record of assent, split the arbitration costs in the employee’s favour, and make it mutual. Each of those addresses a recognised ground of attack, and together they are what makes the agreement worth having.
