The widely used HR tool is used to measure employee absenteeism within organisations. What’s more; the tool is incorporated as a feature within the e-days system.

Frequent, short-term absences are considered to be somewhat more disruptive than long term. Work cover can be more easily arranged as solutions for prolonged absence, but the unexpected upheaval of an employee taking an unplanned day off can put strains on both costs and resources.

The Bradford Factor is formula that calculates an absence score for each employee within an organisation. This is achieved by taking into account the number of instances an employee has been absent, and the total duration of these absences over a 12-month period. As a result, higher Bradford Factor scores highlight absence patterns that are most disruptive and costly to an organisation.

The theory goes that when specific trigger points are reached, further investigation or action should be taken. This helps organisations to draw useful conclusions from their absence management data.


Calculating the Bradford Factor Score

The Bradford factor is calculated using the following Bradford Formula:

B = S² x D


This is where:

  • B is the Bradford Factor score
  • S is the total number of absence instances of an individual over a set period
  • D is the total number of days of absence of that individual over the same set period

A person’s score significantly increases as the number of absence occurrences increase, even if the employee is only off for 1 or 2 days at a time.

Reasons to Exclude

As a general rule, there some reasons for absence that should not be included when calculating an employee’s Bradford Factor score. These include, but are not limited to:

  • pregnancy-related illness
  • time off for dependent care
  • maternity leave
  • paternity leave
  • parental leave
  • ante-natal appointments
  • jury and public service

 Bradford Factor Calculations within e-days

If you don’t have time to calculate your Bradford score manually, e-days can do this for you. Calculations and tracking are automatically carried out for each member of staff, with the highest sickness scores populated as alerts on manager dashboards to notify when action should be taken.

Managers are then able to investigate instances of staff absence further to prevent issues from reoccurring in the future.
