Fatigue Reduction (NR/L2/OHS/003)

If you supply rail labour, Network Rail standard NR/L2/OHS/003 sets hard limits on hours, rest, door-to-door time and fatigue scores. This guide explains each trigger and exactly how Skillo Suppliers enforces it when you assign candidates, send a shifts request, or batch import shifts. For a one-page summary of how each rule is enforced, start with the Rail Fatigue Compliance Guide. For the scoring algorithm itself, see Fatigue & Risk Index (FRI); for travel math, see travel time calculation.

How Fatigue Reduction triggers are integrated into skillo for suppliers.​

✅ More than 60hrs / 72hrs in 7 rolling days​

Switch between 60 and 70 in Compliance settings. Suppliers are not allowed to assign candidates/approve shifts requests that trigger this.

14hrs or more door to door​

When a supplier wants to schedule shifts for a candidates, depending on the value of the Hard door-to-door checks in the Compliance settings either

  • if checked: times are calculated and if there are exceedances then the assign action is blocked

  • if not checked: times are calculated and if there are exceedances the exceedances are created and marked on the shifts

When a subsponsor wants to send a shifts request, they can not send one where the total travel and shift time exceeds 14 hours.

They have to add accommodation address and details. See adding accommodation.

✅ More than 12hrs in one shift/working day​

Suppliers are not allowed to assign candidates/approve shifts requests that trigger this.

✅ Less than 12hrs rest between shifts/working days​

Suppliers are not allowed to assign candidates/approve shifts requests that trigger this.

✅ More than 13 day or nights in 14 rolling days​

Suppliers are not allowed to assign candidates/approve shifts requests that trigger this.

✅ Day time fatigue score (FRI) of 35 or more​

The fatigue index is displayed on all day shifts after assignment.

It is displayed upfront on all calendar pages and also on the shifts details view.

When a supplier wants to schedule shifts for a candidates, depending on the value of the Hard Fatigue and Risk Index checks in the Compliance settings either

  • if checked: fatigue and risk indices are calculated and if there are exceedances then the assign action is blocked

  • if not checked: fatigue and risk indices are calculated and if there are exceedances the exceedances are created and marked on the shifts

✅ Night time fatigue score (FRI) of 45 or more​

The fatigue index is displayed on all night shifts after assignment.

It is displayed upfront on all calendar pages and also on the shifts details view.

When a supplier wants to schedule shifts for a candidates, depending on the value of the Hard Fatigue and Risk Index checks in the Compliance settings either

  • if checked: fatigue and risk indices are calculated and if there are exceedances then the assign action is blocked

  • if not checked: fatigue and risk indices are calculated and if there are exceedances the exceedances are created and marked on the shifts

✅ Risk score (FRI) of 1.6 or more​

The Risk score is displayed on all shifts after assignment.

It is displayed upfront on all calendar pages and also on the shifts details view.

When a supplier wants to schedule shifts for a candidates, depending on the value of the Hard Fatigue and Risk Index checks in the Compliance settings either

  • if checked: fatigue and risk indices are calculated and if there are exceedances then the assign action is blocked

Frequently asked questions​

What is the Network Rail 60-hour fatigue rule?​

Rail staff must not work more than 60 hours in any 7 rolling days (Skillo lets you toggle 60/72 in Compliance settings). Skillo blocks the assignment when a candidate would breach it.

How does the 14-hour door-to-door rule work with accommodation?​

Shift + travel both ways must stay under 14 hours. Adding an accommodation address shortens the calculated journey and can clear the exceedance. Subsponsors must attach accommodation proof on the shifts request itself.

When does Skillo block vs warn on FRI scores?​

It depends on Hard Fatigue and Risk Index checks in Compliance settings: checked = block assignment, unchecked = record the exceedance on the shift. Day FRI 35+, night FRI 45+, risk 1.6+.

Where can I read the full Network Rail standard?​
