The Commission determined that the interpretation of 'continuous service' in two separate agreements in the Western Australian health system was straightforward and corresponded with the definitions provided within the agreements themselves.

The matter concerned a dispute related to the interpretation of clauses in two separate agreements in the Western Australian health system. United Workers Union (UWU) applied for a declaration on the true interpretation of clauses in the Education Assistants' (Government) General Agreement 2023 and the Government Services (Miscellaneous) General Agreement 2023, both of which outlined entitlements to long service leave based on continuous service. The Director-General of the Department of Education was the Employer party to the Education Assistants Agreement, while numerous government agencies collectively represented the Employers in the Government Services Agreement.

UWU argued that 'continuous service' should be understood according to its common-sense, plain English meaning. In contrast, the Employers contended that 'continuous service' referred only to qualifying service since the registration of the industrial agreement containing the casual Long Service Leave clause.

Senior Commissioner Cosentino found that there was no ambiguity in the references to 'continuous service' in the relevant clauses of both agreements. The Education Assistants Agreement and the Government Services Agreement did not contain any ambiguity, and the words in question did not support the interpretation advocated by the Employers. As a result, the Commission provided directions regarding the true interpretation of 'continuous service' in both agreements, clarifying that it aligns with the continuous service specified within each respective agreement's clauses.
