The regulator found something embarrassing in March 2026. The Information Commissioner's Office1 talked to thirty employers about their AI hiring tools and discovered that most of them did not know they were running automated decision-making at all. Not a minority. Most.
Here is what the enforcement case looks like, when it arrives. By the end of 2028, the ICO will have taken action against a UK employer for automated hiring decisions, and the charge will not be that a machine decided. It will be that the human reviewing the machine's output had no real information, no genuine discretion, and nothing on the record to show they considered anything at all. The ICO already has a word for what that person was doing. It calls it a rubber stamp, and it says that is not enough2.
The setup that produces this is worth describing exactly. Seventy-eight percent of UK employers3 run applicant tracking systems. The system sorts and ranks. A recruiter looks at the output. The recruiter decides. The employer points at the recruiter and says: there is your human in the loop. The ICO points back and asks whether that person could have changed anything, or whether they were just countersigning.
Meanwhile Parliament, through the Data (Use and Access) Act 20254, which came into force in February, actually loosened the old near-prohibition on solely automated decisions. The law got more permissive and the regulator got more demanding at the same moment. Neither arm of the state noticed the other was moving.
Now the arithmetic. About 8% of recruiters5 configure their tracking system to auto-reject candidates outright. Seventy-eight percent of employers use these systems. So: 0.78 × 0.08 = roughly six in a hundred UK employers run a gate with no human stop before rejection. The other seventy-two percent rank and sort, with a person nominally choosing afterwards. Yet 38% of UK job seekers6 admit to using prompt injections or hidden text to beat the screen. They are spending hours fighting a machine that, at seven employers in eight, was going to show their application to a person regardless. They have optimised for a threat that touches fewer than one employer in sixteen.
Nobody in this transaction is looking at the same thing. The applicant thinks it is a wall. The employer thinks it is a shortcut. The ICO thinks it is a tribunal. All three are accurate about their own slice of it.
The question the regulator's report left unanswered, and which only an enforcement case will settle, is whether the recruiter looking at a ranked list had anything to work with. Not whether a human was present. Whether the human could have done anything other than nod. The ICO wants involvement that is, in its own phrase, "meaningful and active"2. That is four words standing in for a standard nobody has tested in court yet.
Form has always beaten substance in employment law. The tribunal wants to know if the process ran correctly, not whether the outcome was right. That was true before software and it is true now. The only thing that changed is that the process has become invisible enough that the employer cannot always describe what it was, which is a problem once someone asks.
A 23-year-old is on her ninetieth application this month. She spent three hours on the last one, running it through a tool that rewrites CVs for machine readers. The employer she sent it to uses a tracking system that ranks candidates and passes the top thirty to a recruiter with a two-day window and two hundred other applications. The recruiter saw a list. She never knew.
