The two halves compensate different things: standby pays for the leash — the beer you don't drink, the hike you don't take — while call-in minimums pay for the interruption itself. A rotation that pays only one half is underpricing the other, which is the argument to bring to the negotiation.
A worked example
$2/hour standby across 128 night-and-weekend hours is $256. Two calls at a 2-hour minimum and $30/hour add $120 — the week pays $376. On a one-week-in-four rotation, that's about $4,900 a year for carrying the pager, a number worth knowing when a competing offer claims "no on-call" as a perk.
Negotiating a rotation
The highest-leverage terms in order: the call-in minimum (2 → 4 hours doubles interruption pay), whether minimums stack per call, standby rate on holidays, and rotation frequency. Employers concede minimums more readily than rates — the cost only appears when they actually page you, which aligns everyone's incentives toward quieter systems.
Frequently asked questions
Do employers have to pay for on-call time?
It depends on how restricted you are. If you're 'engaged to wait' (must stay on-site or so restricted you can't use the time freely), that's compensable work time under federal law. Carrying a phone with a reasonable response window usually isn't — which is why standby stipends are policy, not law, in most jobs.
What is a typical on-call stipend?
Common structures: $1–5 per standby hour, a flat $100–400 per week of coverage, or a fraction of base rate (10–25%) for standby hours. Tech and healthcare pay toward the top; the written policy is what counts.
What is a call-in minimum?
A floor on paid time when you're actually called: commonly 2–4 hours minimum at your regular (or overtime) rate, even if the fix took 15 minutes. If you're called three times in a night, whether minimums stack is a policy detail worth knowing before the 2 AM page.
Does on-call work count toward overtime?
Hours actually worked on calls count toward the 40-hour week for non-exempt employees — a heavy on-call week can push regular hours into overtime territory. Standby stipends themselves typically also feed the regular rate used for overtime math.
