Worker fatigue opt-outs

Some fatigue limits are legal hard stops that must always be enforced. Others are internal advisory guidelines where a worker's own informed choice should be respected. Subshift supports this distinction through the canOptOut flag on individual fatigue rule limits.

When a limit is marked as opt-out eligible, workers can choose to opt out of that specific limit from the Subshift worker app. Their opt-out state and full history are tracked and visible in the agency portal.

Warning

Only WARN-severity limits can be made opt-out eligible. BLOCK-severity limits always require a manager override — they cannot be opted out of by the worker.

Enabling opt-out on a fatigue rule limit

  1. Go to Fatigue Rules in the sidebar.
  2. Click the rule you want to edit (or create a new one).
  3. Locate the specific limit you want workers to be able to opt out of.
  4. Set the severity to Warn (if it is not already).
  5. Enable the Can opt out toggle for that limit.
  6. Save the rule.

Note

The canOptOut flag applies to a single limit within a rule, not to the entire rule. A rule can have some limits that workers can opt out of and others that they cannot.

What the worker sees

Once a limit is marked as opt-out eligible, workers see it in the Fatigue settings section of the Subshift worker app. Each opt-out eligible limit is listed with a toggle the worker can turn on or off.

When a worker opts out of a limit, it is no longer applied when the matching engine evaluates their eligibility for shifts. The opt-out does not affect other limits on the same rule.

Viewing opt-out status per worker

To see a worker's current opt-out state:

  1. Go to Workers and click the worker's name.
  2. Select the Fatigue tab on the worker detail page.

The Fatigue tab lists all fatigue rules active for the worker's positions. For any opt-out eligible limits, you can see whether the worker has opted out and when that choice was last changed.

Opt-out history

Every opt-out change — opt in or opt out — is recorded in the worker's activity log with a timestamp. This gives agencies a clear record of when the worker's preferences changed, which can be relevant in regulatory reviews.
