Being Available
Time spent available but not working is the hardest category in the subject, and the answer turns on how much the arrangement constrains the person's life.
Four standby arrangements
| What happens | Required by | Paid? |
|---|---|---|
| On site, in a rest room, must respond in 2 minutes | Rota | Paid |
| At home, must reach site in 30 minutes | On-call rota | Contested |
| At home, phone on, no response time stated | Informal | Contested |
| Phone on, may decline, genuinely optional | Nobody | Not paid |
The test is the constraint, not the activity. All four involve doing nothing; two of them are working time and one is not.
A person who is available but not working is doing nothing in particular, and the intuition that nothing is not work is strong. It is also, in this area, frequently wrong.
The practical lesson in “Being Available” is that a timesheet only becomes reliable through a process people can operate consistently. For teams exploring does microsoft teams track your activity, this reference page can add time and project context, provided collection is proportionate, access is limited and every consequential inference receives human review.
The question is not what the person is doing. It is how much the requirement to be available constrains what they could be doing, and that is a spectrum with a well-developed body of thinking behind it.
For a separate benchmark relevant to “Being Available”, consult the CISA insider-risk mitigation resources. Use it to test record quality, approvals, retention, employee rights and exception handling against the real workflow rather than treating a software report as self-explanatory evidence.
The spectrum
At one end, standby on the employer's premises with an immediate response requirement. The person is at the employer's disposal in every meaningful sense and this is working time more or less everywhere.
At the other, an arrangement where the person may be contacted, may decline, and faces no consequence for being unreachable. Not working time, and not really standby.
The middle is where everything interesting is, and the factors that move a case along it are consistent: how quickly a response is required, whether the person must be in a particular place or within a distance, how often they are actually called, and what the consequences of being unavailable are.
A thirty-minute response time that requires staying near home, with frequent calls, sits much closer to the working-time end than an arrangement with a four-hour window and two calls a year.
What the clock records
Nothing, in nearly every case. Standby happens outside the punch, and the call-out that interrupts it may or may not generate one depending on whether the person goes to a site with a terminal.
So an arrangement that may be substantially working time produces no entry in the system that calculates working time. That is the gap, and it is the reason standby disputes are argued from rotas and phone logs.
Recording it properly
The standby rota itself is the record of availability, and it should be in or feed the time system rather than living in a spreadsheet.
Call-outs need their own record with start and end, created by the person, after the fact. A minimum block — thirty minutes or an hour — is the usual and sensible approach, because a nine-minute call still ends an evening.
Travel to a call-out is working time in almost every treatment, and is the piece most often omitted.
Why it matters beyond pay
Working-time limits and rest requirements. Where standby counts as working time, the hours add up quickly and the rest between duty periods may not exist.
An engineer who worked a full day, was on standby overnight, was called out twice, and is rostered the following morning may be well outside the rest rules. Nothing in the system will show it, because the standby and the call-outs are in different places from the shifts.
This is the argument that gets attention, because the consequence is not a back-pay claim but somebody driving to a site at four in the morning on four hours' sleep.
The payment question, separately
Even where standby is not working time, it is almost always paid something, by agreement or by convention, because the constraint is real.
Two components are worth separating: the availability payment, for the constraint, and the call-out payment, for the work. Arrangements that bundle them produce arguments when the call volume changes, because the bundle was priced for a different frequency.
Reviewing an arrangement
Four questions. How fast must they respond, where must they be, how often are they actually called, and what happens if they do not answer.
Then look at the call frequency over a year. An arrangement designed as rare availability that is being called three times a week is not the arrangement anybody agreed to, and its character has changed whatever the paperwork says.
The one to look at first
Informal standby: no rota, no payment, no agreement, and an expectation that a particular person will answer because they always have.
It has all the constraint and none of the structure, it is invisible everywhere, and it is usually sitting on one or two people who have been doing it for years.
Writing the arrangement down
Most standby arrangements have no document. They have a rota, a phone and a custom, and the constraints — how fast you must answer, how far you may be, whether you may drink, whether you may sleep — exist only as shared understanding.
Writing them down is what makes the category assessable, and it tends to loosen them: asked to state in writing that somebody must be able to attend within thirty minutes, an organisation often finds ninety is sufficient. The constraint was never decided; it was inherited, and it is what determines both the pay question and what the arrangement costs the person.
