Statutes, collective agreements, works agreements and individual contracts may interact. Their relationship depends on the issue and the relevant legal rules.
Clear criteria and accountable decisions
Identify the affected group, existing rules and responsible decision-makers. Statutes, collective terms, works agreements and individual promises need to be considered together. Directors, senior executives and other employees may fall under different rules. A single corporate policy does not remove these differences.
Before implementation, define criteria, procedures and review mechanisms. Selection, pay and personnel decisions must be legally defensible and free of unlawful discrimination. Digital processes require particular attention to purpose, data access and human responsibility. Review representative participation early enough for it to influence the planned arrangement.
Documents and practical implementation
Useful documents include policies, process descriptions, contracts and technical specifications where relevant. Distinguish changes required before implementation from issues addressed through clearer responsibilities or documentation. Training and review of actual practice help maintain compliance. A changed system, purpose or organisation may require a new assessment rather than relying indefinitely on an earlier approval.
Four practical examples
These illustrative situations highlight the issues to examine. The outcome depends on the agreement and the facts that can be established.
Example 1
A contract conflicts with a mandatory statute. Determine which terms can lawfully be agreed.
Example 2
A works agreement regulates a collectively bargained subject. Review statutory limits and any opening clause.
Example 3
A repeated benefit becomes disputed. Assess whether the practice created an entitlement.
Example 4
A contract refers to an external agreement. Interpret the reference and its effect over time.
