If your organisation hires consultants in Sweden, you'll want to keep track of how long each engagement has been running. LAS (short for Lagen om anställningsskydd the Swedish Employment Protection Act) is the law that regulates employment protection, including rules around when time-limited engagements may convert into permanent employment.
In consultant staffing, LAS is often mentioned alongside the "24-month rule" (from the Temporary Agency Work Act). That rule can require the hiring company to offer employment, or pay compensation, when someone has been engaged for a certain length of time.
How Fill helps you track LAS tenure
Fill uses LAS as a tracking and compliance support concept, so you can monitor how long a consultant has been engaged and spot when you may be approaching relevant thresholds.
On the Consultant Card, this is reflected in the Tenure section, including a rolling 36-month perspective. This helps you:
See total assignment history for a consultant
Understand time worked within a defined period
Reduce the risk of missing obligations connected to long-running engagements
Assignment classification matters
To calculate LAS-related tenure correctly, Fill needs to understand what type of assignment it is, for example, whether it's from an independent contractor or a consultant agency. It's also important to know if the assignment is time-based or result-based:
Time — the engagement is compensated based on worked time, typically by an hourly rate
Result — the engagement is compensated based on an agreed outcome or deliverable, often a fixed price for a defined scope
Missing classification data
You may see a prompt saying "missing classification data" on the Consultant Card. This appears because without that data, Fill can't reliably determine what should be included in LAS and tenure calculations. To resolve it, make sure each assignment has the correct classification set.
