This dispute arose as a result of a worker seeking to return to full time working hours. She had worked reduced hours for over a decade but claimed under the terms of this arrangement she had a right to return to full hours. The Court disagreed in finding that this entitlement had long expired, with no right to return at her discretion. However, uncertainty had arisen due to management’s failure to set out the terms of the reduced hours, resulting in the Court finding that the Claimant should be allowed return to full time work when a suitable vacancy arose.
