Who cannot use it
People the method excludes outright, the accommodation that follows, and who signs it off.
People a Method Excludes Outright
Some people cannot use a given biometric at all, permanently. The system treats them as repeated failures, which is wrong and causes most of the harm.
Covering, and What Has to Be Offered
Face systems and religious or cultural covering meet in a doorway at six in the morning. The arrangement that resolves it has to be decided long before.
The Accommodation, and Who Signs It
Giving somebody a different way to clock in takes five minutes. Doing it so that it holds and never has to be re-argued takes a short process.
Agency, Contract and Visiting Workers
The people who cannot use the system are frequently not excluded by their hands but by their contract, and nobody owns the question of what to do about them.
Apprentices, Young Workers and Consent
Where consent is the basis for taking biometric data, a sixteen-year-old apprentice is the hardest case, and most sites have not noticed they have one.
The Person Who Simply Refuses
Somebody objects — not medically, not religiously. They just do not want to give their employer a fingerprint, and the arrangement has to absorb that.
Making the Alternative Not a Penalty
An alternative that exists but is slower, more visible or more awkward is a penalty with a policy attached, and everybody on the floor can see it.
