The Bradford Factor and managing absence.
How the score works, where to set trigger points, and how to tackle short-term absence without falling foul of discrimination law.
What the Bradford Factor is
The Bradford Factor is a simple score that weights frequent short absences more heavily than one long one, on the basis that repeated short spells are more disruptive. It is a prompt for a conversation — not a decision-making machine.
The formula
- Score = S × S × D, where S is the number of separate absence spells and D is the total days absent, over a rolling period (usually 12 months).
- One absence of 10 days: 1 × 1 × 10 = 10.
- Five absences totalling 10 days: 5 × 5 × 10 = 250.
- Ten absences totalling 10 days: 10 × 10 × 10 = 1,000.
Setting trigger points
There is no legal standard. Many organisations use something like 50 for an informal chat, 125 for a formal review and 250 for a stage-one warning under the absence procedure. Choose levels that fit your size and sector, publish them, and apply them consistently. Every trigger should lead to a conversation, never an automatic sanction.
Absences to exclude
- Pregnancy-related absence must be disregarded — counting it is unlawful discrimination.
- Disability-related absence should normally be discounted or the trigger adjusted as a reasonable adjustment.
- Consider excluding industrial injury, hospital treatment and bereavement-related absence.
- Statutory family leave is not sickness absence and should never be scored.
Return-to-work meetings
The single most effective absence measure is a short return-to-work conversation after every absence. It confirms the person is fit to be back, picks up patterns early, shows the absence was noticed, and gives you a written record if a formal stage is ever needed.
Common mistakes
- Treating the score as the decision rather than the trigger for a conversation.
- Including pregnancy or disability-related absence in the score.
- No written absence policy, so trigger points appear invented after the fact.
- Never doing return-to-work meetings, then acting on months of accumulated absence.
Want a hand with this?
If absence is creeping up, we can put a clear policy, sensible trigger points and a simple tracker in place — and coach you through the first few conversations.

In short
- Score = spells × spells × total days, over 12 rolling months.
- Triggers start conversations, not sanctions.
- Discount pregnancy and disability-related absence.
- Publish the policy and apply it consistently.
- Do a return-to-work chat after every absence.
