FA-94176 / Shift rostering labor rules / Open access
Mutually agreed swaps charged predictability pay · case 01
Employer pays premiums for swaps the workers arranged themselves.
ROOT CAUSE
Only worker-initiated changes are exempted.
VERIFIED REPAIR
Exempt both worker-initiated and mutual changes.
Unsuccessful approach: Exempting only mutual changes charges premiums for worker requests.
Case contract
Each change is [kind (add/cut/cancel), notice minutes before the shift, changed minutes, initiator]. Changes initiated by the worker or mutual swaps, or with at least 14 days (20160 minutes) notice, earn nothing. Additions of at least 15 minutes earn 60 premium minutes. Cuts or cancellations earn 60, or max(60, lost // 2) with less than 24 hours notice. Return [per-change premiums, total].
Why this case matters
Fair-workweek predictability pay depends on precise notice thresholds and exemptions.

Verification & scope
Stipulated toy labor rule for a bounded roster model; it is not legal advice and does not claim conformance with any jurisdiction, award, or collective agreement. This reproducer isolates one failure mechanism. Results cover the supplied fixtures. Variants within a family share a test contract and should remain grouped when constructing evaluation splits. Related mechanisms with a shared evaluation_group must also remain together; these controlled models are not independent production incidents.
