“Guaranteed hours” can be one of the most reassuring phrases in a nanny job offer. It can also leave important questions unanswered. Before you rely on that promise, establish which schedule it covers, what happens when plans change, and how the arrangement will appear in your written offer.
The useful conversation is practical: if the family does not need you on an agreed workday, what happens to that day's pay and your availability? Work through several examples with the recruiter. A clear answer should describe the actual proposed arrangement rather than simply repeat the phrase.
Start with the agency's definition
Nannies Plus explains guaranteed hours as payment for the regular schedule when a family's needs change. It distinguishes this from the nanny's own time off. That is the agency's explanation, not a universal legal rule.
Ask your recruiter to explain what the term means in this particular offer. Does it refer to named days and times, a weekly total, or something else? Which document contains the commitment? If the job posting and offer use different wording, request a reconciled version before deciding.
Avoid treating “we always look after our nanny” as the answer. A family can have good intentions and a different understanding of what happens during a school holiday or cancelled trip. Your goal is a shared description that remains understandable when everyone is busy.
Identify the schedule being reserved
Put the proposed workweek on a calendar. Record start and finish times, regular days off, and any recurring evening commitment. Then ask whether the guarantee attaches to that schedule or whether the family expects to move the hours around.
For example, a weekday arrangement and a changing weekly rota create different availability commitments, even if their totals match. If changes are expected, ask how much notice you will receive, who confirms them, and what happens when a proposed change conflicts with an existing commitment.
Do not assume that reserving a weekly total means reserving every hour of every day. Equally, do not assume a job described as flexible has fixed days. State your actual availability and ask the recruiter to test it against the family's requirements.
Walk through changes one at a time
Use scenarios that distinguish whose plans changed. The family coming home early, travelling without you, cancelling an outing, and asking you to take an afternoon off are different situations from your requesting personal time away.
Ask what the offer says about each situation. Include a week when the family wants additional work after using less of your scheduled time earlier. Rather than agree casually to “making up hours,” request an explanation of the proposed scheduling and payroll treatment, with appropriate local review where needed.
Also ask about predictable changes. If the children will attend camp for several weeks, that is useful to discuss before accepting, not after the schedule drops. Put known closures, travel and school transitions beside the proposed guarantee so the recruiter can identify gaps.
Clarify what you do when the children are away
A family may still want agreed work completed during its absence. Ask for the specific duties and location rather than accepting “anything that needs doing.” Child-related organising, errands, pet responsibilities and general household work should not become interchangeable simply because the children are elsewhere.
Have the recruiter distinguish three possibilities: you are released from work, you remain available during the normal schedule, or you perform specified duties. If you are released, ask how that will be communicated and whether a later recall is contemplated.
The US Nanny Association's interview questions include guaranteed hours and unexpected family-initiated days off. Use those prompts to open a discussion, then document the answer specific to your job.
Use a guarantee review worksheet
Create one page with the following headings. Under each, record the answer, where it appears in the offer, and any unresolved question. This is an original preparation tool, not contract language.
- Reserved schedule: Which days and times am I committing to keep available?
- Family cancels: What happens if I am ready to work but the family does not need me?
- Family travels: Am I released, available, travelling with them, or doing listed duties at home?
- I request leave: Which separate leave provision applies, and how is approval recorded?
- Schedule moves: How are proposed changes handled when I cannot accommodate them?
- Additional work: How will extra hours be approved, recorded and reviewed for payroll?
- Written confirmation: Who will revise the offer, and when can I review it?
Label unanswered items “open.” Do not fill them with your preferred interpretation. A neat worksheet with an inaccurate assumption is less useful than a short list of questions the recruiter can resolve.
Fictional example: the cancelled holiday week
Fictional example: Ana receives an offer describing a regular Monday-to-Thursday schedule with guaranteed hours. During a call, the family mentions taking the children away for a week. Ana initially assumes she can use that week for her own trip.
Her recruiter clarifies that the family wants her available for agreed child-related organising on two of those days. Ana explains that she needs to know whether a family absence means release from work or a different assignment. The recruiter returns with a revised description of the duties, schedule and release process.
Ana can now decide whether the arrangement works. The useful outcome is not that one interpretation won. It is that neither side starts the job relying on a different calendar. Before accepting your own offer, ask for the same clarity and read the revised wording alongside the separate leave and scheduling terms.
