Calculating the sick absence percentage in reports in Simployer Classic

Modified on Mon, 11 Aug at 1:51 PM

For Sick leave reports in Simployer Classic we calculate the Sick percentage base on this:


Possible work days (possible man labour days)

Norwegian: mulige dagsverk

When calculating the sick absence percentage, possible work days is the divisor in the equation. Possible work days is the number of days in a period a person could have been to work.

If a person has 12 possible work days, and has been sick 3 of these days, the sick absence percentage for this period is 3/12 = 25%.

When calculating possible work days, we have to look at the calendar, and subtract all holidays and non-working days. In the sample above, for a company that doesn't work in the weeked, we have 19 possible work days (2, 3, 4, 7, 8, 9, 11, 14, 15, 16, 18, 22, 23, 24, 25, 28, 29, 30, 31).

If an employee was on a vacation the whole week number 22, the number of work days would be 19-4 = 15.

If an employee had her first employment in the company Monday 14th of May, the number of possible work days is 12.

If an employee ended his employment Friday 18th, the number of work days would be 11.

If an employee is employed in a 50% position, the number of work days in May would by 19 * 0,5 = 9,5

If an employee changed her position in the company from 50% to 100% on the 28th, possible work days would be 15 * 0,5 + 4 = 11,5.

If an employee is sick more than 52 weeks (past the max date registered on the sick absence), the days past this date will not count as possible work days.


In the leave module, the customer can define absence types that affect the sick absence statistics. In the image below, when this absence type is registered, it will reduce the possible work days for the period the absence is valid:

Also, the customer can choose to set up the absence type so that the absence perventage on the leave should also be registered. In this case, the percentage on the leave will have to be taken into consideration when calculating possible days. If this is not selected, it should be considered to be a 100% leave:

To sum things up:

1Non-working days are not counting in the number of possible work days
2Vacation days are not counted
3To get possible work days, the work days is multiplied with the position percentage.
4Work days are only calculated for the period where the employee has employment.
5If the position percentage changes in the period, this will affect the number of possible work days.
6Work days past the maximum date regsitered on the sick absence do not count as sick days.
7Absence from the leave module can affect the sick absence statistics.
