What we do
Sensitive-content review
Some of the work machine learning needs means looking at things nobody should have to see, so that fewer people have to see them later. We do it, and we organize everything else around the people doing it.
Content tiers
| Tier | What it means | Where | Wellbeing time a month |
|---|---|---|---|
| S1 | Occasional distressing material within mostly ordinary content | Open floor or Rungwell at Home | 2 hours |
| S2 | Regular distressing material: violence, hate, sexual content, self-harm | Open floor, separate team; not at home | 4 hours |
| S3 | Sustained exposure, or data under strict confidentiality | Restricted rooms only | 8 hours, plus 10 minutes every hour |
- Every labeller on S2 and S3 work has an on-site counsellor, a quarterly check-in, and the right to move off the project without losing pay for the shift.
What we review
We label and review user-generated posts, images and video against a platform’s own policies, and build the labelled sets that platforms use to train and test their classifiers. We do not decide what a platform’s policy should be, and we do not take enforcement decisions on its behalf.
Material that appears to show the abuse of a child is never assigned for labelling. If it reaches a queue, it is removed at once and escalated under the client’s reporting procedure, and the labeller who saw it is offered a counsellor that day.
The rooms
Both centres have restricted rooms with their own access control, phone lockers at the door, no windows onto the open floor, and a counsellor’s office next door. S3 work is never done through Rungwell at Home.
What we are changing
Labellers told us in 2025 that our wellbeing program is better on paper than on a busy shift. An independent review of the program is under way; see Wellbeing.
