Britain’s retail payroll has never been smaller. 2.78 million jobs on a four-quarter average in the year to the second quarter of 2026. That is 122,000 down on two years ago, and part-time work is at its lowest on record. The wage bill has been charged with all of it. The wage bill explains why the roles went; it does not explain why nobody is hiring them back.

The arithmetic is not in dispute. Trade coverage of the figures led on National Insurance and two above-inflation rises in the National Living Wage: £6.5 billion in two years. It quoted the BRC on entry-level jobs “vanishing at the very moment they are needed most”. Not one machine appeared in the account. Retailers’ own trading updates have not managed that restraint.

The charge fell unevenly, which is the part worth reading twice. Fifty-five per cent of retail roles are part-time, so the lower contributions threshold pulled short-hours staff into employer National Insurance for the first time. Over two years the cost of a part-time role rose 19 per cent, against 15 for a full-time entry-level one. The steepest rise landed on the shortest shift. That shift is the unit a scheduling system exists to delete.

A tax that raises the price of an hour also raises the value of the machine that removes it. In the weeks after the 2024 Budget’s National Insurance rise, one retail boss told the Guardian that the increase had suddenly made electronic shelf labels economically viable. Currys planned electronic pricing for 100 of its 300 British shops within the year. Almost a third of retail finance directors said they would answer the same cost rise with more automation, a response that ranked behind raising prices, cutting head office jobs and reducing working hours. That Budget did not cut those jobs. It repriced them against equipment.

By last winter, in a separate BRC survey of finance chiefs taken ahead of the 2025 Budget and the Employment Rights Act, the intention had hardened. The survey found 61 per cent planning investment in automation, 68 per cent pursuing higher productivity and 52 per cent planning to cut hours or overtime, against 32 per cent who expected to reduce store headcount. Nearly twice as many meant to install something as meant to dismiss anyone, which is roughly how a workforce disappears without a redundancy notice. A post does not need abolishing once the rota stops asking for it.

A tax can be reversed at a Budget; a rollout cannot.

Seasonal hiring is where the decision shows first, because it is the only headcount a retailer builds from zero every autumn. Permanent vacancies can go unfilled without anyone counting them. A Christmas intake has to be advertised, which means somebody publishes the number.

Last September the John Lewis Partnership advertised 13,700 Christmas roles across 315 Waitrose shops and 35 John Lewis stores. It called the drive the largest seasonal recruitment it had ever run.

This September it advertised 10,400, across 320 Waitrose shops and 36 John Lewis stores. Six more shops, 3,300 fewer seasonal hands. The announcement credits investment in shops and in new technology “designed to free up Partners’ time to focus on serving customers”. Freed-up time is precisely what a seasonal contract used to buy.

One partnership in one December settles nothing about 122,000 jobs. It does make the trade body’s request harder to read. The BRC wants the threshold lifted to £6,000 so retailers can “invest, hire and give thousands more young people that vital first step”. The Autumn Budget may grant it. The money will reach businesses that decided some time ago what it was for.
