What is the ideal on-call rotation length?

Most SRE teams use weekly rotations as the standard. Daily rotations are too disruptive, while bi-weekly or monthly rotations lead to skill atrophy. Weekly rotations balance context retention with burnout prevention.

What is a shadow on-call rotation?

A shadow rotation pairs new engineers with experienced on-call responders. The shadow observes and learns incident response without being the primary responder. This is essential for onboarding and maintaining team resilience.

How many people should be in an on-call rotation?

A healthy on-call rotation has at least 5-6 engineers to ensure each person is on-call no more than once every 5-6 weeks. Smaller teams risk burnout; larger teams may lose incident response skills from infrequent practice.

Should on-call engineers get compensated differently?

Yes, many companies offer on-call compensation through extra pay, comp time, or reduced meeting load during on-call weeks. Fair compensation improves morale and reduces attrition.

Why On-Call Design Matters

A poorly designed on-call rotation leads to burnout, attrition, and slower incident response. Engineers who are constantly on-call become fatigued and start ignoring alerts.

The best on-call systems have clear escalation paths, fair distribution of load, and built-in training through shadow rotations.

The Golden Rules

Aim for 6+ in the rotation — Reduces frequency and burnout (e.g., ~1 week every 6+ weeks).

Weekly rotations — Long enough to build context, short enough to prevent burnout.

Always have a backup — Secondary on-call catches what primary misses.

Shadow new engineers — Never throw someone into on-call without training.

Rotation Layer Types

Best-in-class on-call systems use multiple layers for resilience

Primary

First responder. Gets paged immediately. Expected to acknowledge within 5 minutes.

Secondary

Backup responder. Escalates when Primary doesn't acknowledge within your policy (commonly 5–10 minutes for high severity).

Shadow

Training role. Joins incidents to learn without response responsibility.
