Measurement of absenteeism

​The greatest difficulty that companies have in measuring absenteeism is that there is no homogeneous absenteeism rate to be used at national level, which prevents comparison between different organisations. In addition, the only comparative index that currently exists is the Classification of Economic Activities (CNAE), but it has its shortcomings as a single CNAE groups sometimes incomparable companies.

Calculation of the Absenteeism rate

It is calculated as a percentage relationship between the number of lost days (total of hours not worked due to occasional causes) on effective negotiated days in the company (total of possible working hours).

Absenteeism rate
=

Total non-worked hours for occasional causes(Days lost)

divided by

Total possible working hours(Effective negotiated days)

x 100
  • Non-worked hours (for occasional causes): Hours not worked due to holidays and bank holidays and hours for Temporary Labour Force Adjustment Plans are excluded. ERTE's.
  • Effective negotiated hours: Sum total of negotiated hours and overtime hours, excluding hours not worked due to holidays and bank holidays and hours forERTE's.

Other Absenteeism rates

Starting from this general concept, other more specific indices can be drawn up.

Total Rates (medical absenteeism and non-medical absenteeism)

Momentary Work Absenteeism Rate

Number of absences at a certain moment in regard to the number of workers in the study multiplied by one hundred.

Absolute Work Absenteeism Rate

The percentage ratio between the days of absence of employees in regard to the sum total of days worked, plus the theoretical planned working days.

Disability rate

Number of days lost per employee and year, divided by the number of employees.

Legal Absenteeism rate

Number of lost hours due to paid absences divided into the number of theoretical hours to be worked multiplied by 100.

Personal Absenteeism rate

Number of lost hours due to unpaid absences divided into the total number of working hours available multiplied by 100.

Permanence rate

Actual percentage of presence. This is obtained from deducting from one hundred the sum total of the legal and personal rates.

Temporary Disability rates

Occupational accident rate
Incidence rate
Ii
=

No. of work-related accidents with sick leave x 105

divided by

Average no. of workers exposed

The number of workers is the average no. of workers exposed to risk for the reference period.

Number of accidents with sick leave occurring during the working day (excluding in itinere accidents) per workers exposed to risk.

Accident frequency rate
If
=

No. of work-related accidents with sick leave x 106

divided by

Total no. of hours actually worked

Number of accidents during the working day (excluding in itinere accidents) occurring per million hours worked

Accident severity rate
Ig
=

No. of days not worked due to work-related accidents with sick leave x 103

divided by

Total no. of hours actually worked

Average length of sick leave
DMB
=

No. of days not worked due to work-related accident with sick leave

divided by

No. of work-related accidents with sick leave

Rates for Non Work-related Injury and Non-occupational Disease
Illness frequency rate

The percentage ratio between the number of illness processes in regard to the company's average workforce volume.

Illness severity rate

Percentage ratio between the number of days lost due to illness and the number of processes

Disability rate

Ratio between the number of working days lost due to illness in regard to the average workforce volume, multiplied by 100.

Measurement of absenteeism absences due to temporary disability at FREMAP

FREMAP provides its member companies reports on temporary disability which define the following rates.

Rate of IT TOTAL

This is the percentage ratio between the days of sick leave in the period selected for work-related and non-work-related accidents and illnesses over the course of the employee's relationship with the company and the theoretical number of working days for FREMAP-member companies with both types of coverage.

Rate of IT due to Occupational Accidents or Diseases

It is the percentage ratio between the days of sick leave within the period selected due to work-related injuries or diseases during the employee's work relationship on the theoretical days worked of the companies which have work-related injury or disease coverage with FREMAP.

Rate of IT for Non-work-related Injury or Disease

It is the percentage ratio between the days of sick leave due to common contingencies within the period requested during the employee's work relationship at the company on the theoretical working days of the companies which have common contingency coverage with FREMAP.

Other rates calculated by FREMAP
Pregnancy and Breastfeeding Risk Rate

Pregnancy and Breastfeeding Risk Rate: This is the percentage ratio between the days of provision due to Pregnancy and Breastfeeding Risk of the workers of under 50 years of age and the theoretical working days in the companies who have work-related injury or disease coverage with FREMAP.

Incidence rate

This is the percentage represented by the days lost due to work-related injuries occurring in the working day on the company's average workforce volume . Is it provided in monthly and aggregate terms.

Severity index

This measures the average duration of each absence. This is the ratio between the number of days lost due to work-related or non work-related injury or disease and the number of absences.

Percentage awaiting medical discharge

This is the percentage that represents the monthly average of pending discharges (accident or illness) divided into the number of workers.

Common Contingency Frequency Rate

This is the percentage represented by days lost due to common contingencies on the company's annual average workforce volume.
