The call, up front. Zero-hours contracts (jobs with no guaranteed hours) work for employers because they offload the risk of uneven demand onto workers as unpredictable income. Scheduling apps optimized the flexibility and never touched the guarantee, so the instability stayed. Now the UK has legislated: the Employment Rights Act 2025 will force employers to offer guaranteed hours. The gap is the model that delivers worker income security and keeps the demand-matching flexibility (staffing to match demand) employers actually need.
The gap
The structural imbalance is bargaining power: employers set unpredictable schedules, workers absorb the swings in income. Software made the rota (the staff schedule) efficient and left the guarantee untouched. The real blocker is a model that delivers income stability without erasing the demand-matching employers rely on.
The buyer is obvious and concentrated. Build the income-guarantee layer for shift-based employers (starting with hospitality) and you sell into the exact sectors the mandate hits hardest, before the 2027 duty forces a scramble.

The move
Regulation is about to make income guarantees mandatory, not optional. Software made the rota efficient but left over a million workers unsure what they’ll earn next week. Whoever builds the guaranteed-hours model (income floors, demand pooling across employers, compliant flexibility) sells into every shift-based employer, and into the most exposed sectors first, before the 2027 duty forces the scramble.
