Wiluszynski v London Borough of Tower Hamlets
Wiluszynski v London Borough of Tower Hamlets [1989] ICR 439 is a UK labour law case concerning the contract of employment. It held that if an employment was only partly performed due to a strike, this could be construed as not completing an entire obligation, so that even if an employer has received much more value, they need to pay nothing.
