Measures the absenteeism rate by departments.

Calculation steps:

1. choose time frame
2. identify the total number of working days for employees in each department
3. identify the number of days lost due to the phenomenon of absenteeism for employees in each department.
4. divide number of days lost due to absenteeism by the total number of working days available.
5. express the value as a percentage.

Example:

Time frame: 1st of July to 31st of July

Working days in time frame: 23 days

No. of employees in time frame: 100 out of which

1. 30 are in Sales
2. 70 are in Production

No. of days lost by employees: 50

1. 20 are lost by Sales
2. 30 are lost by Production

Total no. of working days in time frame for Sales department: 30 x 23 = 690

Sales absenteeism rate = (20 / 690) x 100 = 0.028 x 100 = 2.8%

Total no. of working days in time frame for Production department: 70 x 23 = 1610

Production absenteeism rate = (30 / 1610) x 100 = 0.018 x 100 = 1.8%

Note:

If the number of employees in the time frame fluctuates due to employees leaving or joining the company you should calculate and use in the formula the average number of employees within the time frame.

Average no. of employees = (no. of employees at the start of the time frame + no. of employees at the end of the time frame)/2
