"Therefore an emphatic denial by the employer of his obligation to pay the agreed salary or wage, or a determined resolution not to comply with his contractual obligations in relation to pay and remuneration, will normally be regarded as repudiatory.

"However an apparently slight change imposed on a reluctant employee by economic pressure exercised by the employer should not be confused with a consensual variation, and in such circumstances an employee would be entitled to treat the contact of employment as discharged by the employer's breach. In the present case, the amount in issue was not in the context of the overall package very great, although the sums at stake were not trivial. However the refusal to pay was deliberate and determined, motivated by a desire improperly to pressurise the defendants into harder work. The decision wholly undermined the contract of employment and constituted a repudiatory breach."
