The News
The government has published extra evidence to its consultation on ending 'one-sided flexibility', conceding the zero-hours and guaranteed-hours reforms could impose a net cost of £300m to £1.4bn a year on UK business — £3bn to £14.1bn over a decade — with costs climbing sharply as the guaranteed-hours threshold rises, from £340m a year at a 24-hour threshold to £1.2bn at 40 hours. The REC's Neil Carberry called the figures an underestimate, pegging the cost at up to £8m a day, while RSM's Charlie Barnes said employers are already abandoning zero-hours contracts in practice and that retail is shifting to agency workers to avoid the administrative burden.Why It Matters
This is a flexible-resourcing story as much as an employment-law one. The guaranteed-hours provisions in the Employment Rights Act will change how you staff seasonal, peak and variable demand, and the threshold ministers pick — 20, 32 or 40 hours — materially changes the bill. RSM's observation that retail is already migrating to agency workers is a signal that your contingent labour budget and agency strategy are directly in the firing line, whatever the final rules say.Taking Action

Who to talk with in your enterprise
Your workforce-planning lead: model your variable-hours headcount against the 20-, 32- and 40-hour threshold scenarios and price guaranteed hours at each. Your finance partner: treat the £300m–£1.4bn range as a planning input and stress-test your contingent and agency budget. Your legal lead: confirm the consultation's position on whether agency workers stay inside or outside scope.Inspect
What to take a closer look at
Map your zero-hours and low-hours workforce by weekly-hours band. For each band, estimate the cost of guaranteeing hours at the three thresholds, and separate roles that genuinely carry variable demand from those that are fixed hours wearing a zero-hours label — the latter are the ones the reform will simply reclassify and charge you for.Reflect
What to think about more deeply
If your workforce plan only works because a cohort of staff are on zero-hours contracts, are you hiring flexibly — or just deferring the cost of a real headcount decision?
