Can I Ask About Availability for Overtime or Weekend Work?

“I run a building company and sometimes we need people to work weekends to finish urgent projects. Last month I had a brilliant candidate but didn’t know how to ask if he’d be available for weekend work without it sounding discriminatory. Can I ask about overtime and weekends in interviews, or is that opening a can of worms?”

Short answer: yes, you can absolutely ask about availability for overtime and weekend work. If these are genuine requirements of the role, you’d be mad not to ask - it’s better for everyone that candidates know what they’re signing up for.

But there’s a right way and a wrong way. Get it wrong and you could accidentally discriminate against people with caring responsibilities, religious commitments or other protected characteristics.

When You MUST Ask About Availability

If your business genuinely requires flexibility, asking isn’t just allowed - it’s essential. That’s the case when:

• Weekend work is a regular requirement - retail, hospitality, any business operating seven days a week
• Overtime is genuinely needed - seasonal peaks, project-based work, covering colleagues during busy periods
• On-call responsibilities exist - IT support, maintenance, emergency response roles
• Travel or irregular hours are involved - sales roles, field engineers, client-driven schedules

The key word is “genuine”. You can’t ask about weekend availability just because it might be handy occasionally - it needs to be a real, demonstrable requirement of the role.

How to Ask the Right Way

Good:

Availability questions that work

This role requires working alternate Saturdays to provide customer cover. Are you available to work Saturdays? During our busy season (April to August), we typically need five to ten hours of overtime per week. Can you accommodate that? The position involves being on-call one weekend per month for emergency callouts. Are you able to fulfil this requirement?

Not so good:

• “Are you free weekends?” - too vague, free for what?
• “Do you have family commitments that might affect your availability?” - straight into personal territory
• “Young people like you don’t mind working weekends, right?” - age discrimination
• “As a man, you probably don’t have the same childcare issues as women” - sex discrimination, and incredibly stupid

The Four Rules

1. Ask everyone the same questions - you can’t probe men’s weekend availability but not women’s
2. Focus on the job, not personal circumstances - “Can you work Saturdays?”, not “What do you do at weekends?”
3. Be specific about requirements - explain exactly what the role involves
4. Avoid assumptions - don’t presume someone can or can’t work certain hours based on age, gender or family status

The Indirect Discrimination Trap

Here’s where it gets tricky: even if you ask everyone the same question, your requirements could still indirectly discriminate against groups disproportionately affected - people with religious commitments, single parents with caring responsibilities, or people with disabilities needing regular medical appointments.

That doesn’t mean you can’t have the requirements - but you need to show they’re genuinely necessary for the role, and that you’ve considered whether there are other ways to meet your business needs.

When Religious or Cultural Needs Come Up

If a candidate says they can’t work certain days due to religious observance, genuinely consider whether you can accommodate them: shift swaps with colleagues, adjusted working patterns, alternative cover arrangements. You don’t have to agree to every request - but you do need to properly consider whether accommodation is possible without significant disruption.

A real example: a retail client needed Saturday cover. A candidate said she couldn’t work Saturdays for religious reasons. The owner’s first instinct was to reject her. Instead, we explored options - and it turned out other staff were happy to work Saturdays in exchange for a different day off. She became one of their best employees. Always explore accommodation before writing someone off.

The Overtime Question

Overtime needs careful handling because it affects work-life balance and family responsibilities:

Smart: “We’re usually busy between March and June, which often means 45-50 hour weeks. Is this workable for you?” “Sometimes we need people to stay late to finish urgent orders - are you generally available for that?”

Not smart: “We expect 100% dedication - work comes first.” “Hope you don’t have too many hobbies!” “The last person worked 60-hour weeks no problem.”

Be honest about requirements while showing you understand people have lives: “We do need flexibility during busy periods, but we give as much notice as possible and make sure people get time back when things are quieter.”

Zero-Hours and Flexible Arrangements

If you’re using zero-hours or very flexible contracts, discuss availability thoroughly: their minimum viable hours for financial planning, how much shift notice they need, regular commitments, and whether they prefer consistent or varied hours. Be upfront about the reality so there are no nasty surprises on either side.

When Availability IS a Valid Reason Not to Hire

Valid: they can’t work your core hours, can’t cover your busiest periods, or can’t meet genuine travel or on-call requirements. Knowing upfront beats discovering it later.

Invalid: assuming they’ll be unreliable because they have children, disliking their religious commitments, or thinking they’re “too old” for irregular hours. The first set is about the job; the second is about your assumptions - and only the second gets you sued.

Cover Your Back

• State it in the job advert - “Weekend work required” or “Occasional overtime necessary”, clearly
• Document why the requirement exists
• Ask consistently - same questions for all candidates on a role
• Record responses - what candidates said and any accommodations discussed

The Bottom Line

Ask openly, honestly and consistently about genuine requirements - good candidates want to know what they’re signing up for. Focus on the job, treat everyone the same, and consider reasonable accommodations where they exist. That’s the whole game.
