⚙️LAS – Calculation details in depth

Calculation for Temporary position (VIK)

The calculation for VIK does the following:

• defines the period by checking the date five years back from the calculation date,
• totals the VIK days in the period and
• checks whether the VIK days exceed the threshold of two years (number of days set per respective personnel category).
  
  

Calculation for Special fixed-term employment (SÄVA)

According to the Employment Protection Act 5a §, a special fixed-term employment becomes a permanent employment when the employee has been employed with the employer in such a position for more than twelve months in total

• within a five-year period or
• during a period when the employee has had fixed-term employments with the employer in the form of special fixed-term employment, temporary position or seasonal employment, and the employments follow consecutively. This option is called the Chain rule in Flex HRM.

The basis of the calculation for SÄVA does the following:

• defines the period by checking the date five years (see also the section below on the transition rule) back from the calculation date,
• checks the date from which you have had continuous employment based on the calculation date (regardless of whether the employment is active on the calculation date). As continuous employment, employments with SÄVA, VIK and Seasonal employment are counted, according to the tick boxes on types of employment, with a maximum gap of six months. The Chain rule allows you to find SÄVA days further back in time than five years, but you only count SÄVA days – see separate sections below on the Chain rule and transition rule,
• totals the SÄVA days in the period and
• checks whether the SÄVA days exceed the threshold of twelve months (number of days set per respective personnel category).
  
  

SÄVA Chain rule

The Chain rule is calculated based on whether:

• the from-date of the period is at most five years back. Five years means 365 * 5, as a year is counted as 365 days and
• the period is continuous with the previous period with a maximum gap of six months. Six months means 30 * 6, a month is counted as 30 days.
  
  

Three or more occasions – Calculation of intermediate periods for SÄVA

Employees who have had three or more SÄVA days in the same calendar month may count the time/days between the first and last worked day. This applies regardless of whether the calculation is based on calendar days or work days.

In the example below, the employee has three SÄVA days/employments for the period Monday to Sunday 1–7 September 2025.

Example 1 = 3 Employment days

Example 2 = 4 Employment days

Example 3 = 7 Employment days

In the article about Settings and Calculation details there is information about the function Enhanced occasion management which makes it possible, when calculating by work days, to adjust how occasion management for intermediate periods should work with SÄVA.

Transition rule from AVA to SÄVA

When new regulations in LAS started to apply on 1 October 2022, certain transition rules were included. A transition rule means you may count General fixed-term employment (AVA) from 2022-03-01 onwards. This means that you must tick the employment type AVA to count as SÄVA for HRM to take the transition rule into account.
