Maternity Rights If You Work in Construction

‍‌‌‌​​​‌‌​​‌​‌‌​​‌‌​‌​‌​​​​​​​‌​‌‍# Maternity rights if you work in construction

You've got proper maternity rights in law, and they apply on site just as much as in an office, the fact you're in construction just changes how your employer has to manage the risks, not whether they have to. The hard bit is that short contracts and macho culture can make you feel like you don't, so this is about what the law says and how to use it in the real world.

Quick rule of thumb: being pregnant on site doesn't mean you've suddenly become "useless": it means your employer has to use their head, move you away from the risks, sort you proper rest facilities, protect your income where they can, and not quietly bin you because you're having a baby.

1. Risk assessment on site, what must change when you're pregnant

The legal duty

Once you tell your employer in writing that you're pregnant (or have given birth in the last 6 months, or are breastfeeding), they have specific duties under the Management of Health and Safety at Work Regulations 1999, Regulation 16.

They must:

• Assess the risks to you and your baby from your work.
• Change your work or conditions to remove those risks where possible.
• If they can't remove the risk, offer suitable alternative work on the same pay.
• If that's not possible, suspend you on paid leave for as long as needed to protect you.

HSE calls out "new and expectant mothers at work" as a specific category needing extra protection, it's not optional.

Construction tasks that are obvious red flags

HSE lists common risks for pregnant workers and new mothers, several are everyday construction tasks:

• Working at height · increased risk of serious injury if you slip or faint; growing bump affects balance. They should reduce or remove height work for you · especially on ladders, scaffolds, roofs, MEWPs.
• Manual handling / heavy lifting · pregnant and post-natal workers are at much higher risk of back injury and strain from lifting. HSE guidance says pregnant workers "should not lift heavy loads" and employers may need to reduce physical work or provide mechanical aids.
• Vibration · whole-body vibration (plant, rough ground) and hand-arm vibration (breakers, grinders) are called out as risks that may need extra controls or removal.
• Chemicals, dust, fumes · solvents, isocyanates, lead, silica dust, cement, welding fume · all need a proper COSHH look with your pregnancy in mind. They may need to move you away from high-exposure tasks (spraying, cutting, grinding, mixing resins) or beef up controls.
• Heat, cold, long shifts and night work · heat stress, dehydration, long hours and night shifts can be harder to tolerate and increase risk. Employers should think about shorter shifts, more breaks, shade/shelter and flexible hours.

On top of that, PPE may stop fitting safely · risk assessments should also consider whether your PPE is still suitable and, if not, provide alternatives.

If they can't make your normal tasks genuinely safe, they need to move you or pay you to be off.

2. Rest, facilities and antenatal appointments

Rest facilities

Under the Workplace (Health, Safety and Welfare) Regulations 1992, employers must provide suitable rest facilities for pregnant and breastfeeding workers.

On a site that means:

• A clean, quiet space where you can sit or lie down if needed · not just the canteen full of lads swearing and smoking outside.
• Somewhere you can put your feet up on breaks, and, if breastfeeding on return, somewhere private to express and store milk.

Guidance stresses employers must "discuss provision for a suitable area where pregnant and breastfeeding workers can rest".

Paid time off for antenatal appointments

You're entitled to paid time off to attend antenatal appointments recommended by your doctor, midwife or health visitor (for employees, not casual workers).

• That includes scans, midwife checks and some classes.
• Your employer can ask for reasonable evidence (appointment card) after the first one, but they can't refuse reasonable time off or make you make it up.
• If you're on short-term/fixed-term contracts, you still have that right while your contract runs.

3. Maternity leave, pay and coming back

Statutory maternity leave, everyone who's an employee

If you're an employee, you're entitled to 52 weeks' maternity leave (26 weeks Ordinary, 26 weeks Additional), regardless of how long you've worked there.

• You don't have to take the full year, but you must take 2 weeks after birth (4 for factory workers).
• Workers who are genuinely self-employed don't get maternity leave, but may get Maternity Allowance via DWP instead · important if you trade as a sole trader on CIS.

Statutory Maternity Pay (SMP), who qualifies

To get SMP from an employer you must:

• Be an employee, not self-employed.
• Have 26 weeks' continuous employment with that employer up to the end of the 15th week before the baby is due (the "qualifying week").
• Earn at least the lower earnings limit on average.

SMP is 39 weeks' pay if eligible:

If you've been moved around on short fixed-term or agency contracts, you may not hit the 26-week continuous employment test with a single employer, in that case you're likely looking at Maternity Allowance, not SMP.

Fixed-term employees are still entitled to maternity leave and protection. Non-renewal because you're pregnant can be pregnancy discrimination.

Right to return to work

• If you take up to 26 weeks leave, you have the right to return to the same job on the same terms.
• If you take more than 26 weeks, you still have the right to the same job, or, if that's genuinely not possible, a suitable alternative on no worse terms.

Ending or failing to renew a contract because of pregnancy or maternity can be unlawful under the Equality Act.

4. Pregnancy discrimination, what it looks like in construction

Section 18 of the Equality Act says it's unlawful to treat a woman unfavourably because she is pregnant, she has a pregnancy-related illness, or she is on or has sought maternity leave.

In construction, that often shows up as:

• Being taken off decent jobs or site roles after you disclose pregnancy, without a risk-based reason.
• Contracts suddenly not renewed when they otherwise would have been, or you're told "there won't be work for you after your due date".
• Being pushed to resign instead of being offered alternative work or paid suspension.
• Being frozen out, harassed, or treated as a problem because of pregnancy-related sickness or appointments.

Because pregnancy discrimination doesn't require a comparator and the "protected period" is clear, tribunals tend to take it seriously, if the timing stinks, employers have an uphill battle.

5. Practical reality in construction

Short contracts and subcontracting make all this harder in practice, but you still have some levers.

When to tell your employer

Legally, you must tell them by the 15th week before the baby's due to get maternity leave/pay, but for safety you should tell them as soon as you reasonably can so they can do a proper risk assessment.

Tell them in writing (even if it's a short email) so the Reg 16 duties and anti-discrimination protections are clearly triggered.

How to handle site risks day-to-day

• Ask specifically for a pregnancy risk assessment and walk the site with them · highlight height work, heavy lifting, vibration, chemicals, long shifts and PPE fit.
• If they say "it's fine, just be careful", calmly remind them Reg 16 requires them to assess and remove or control risks, not just tell you to crack on.
• If they can't give you safe adjustments, remind them the next steps are alternative work on the same pay, or paid suspension.

If they start pushing you out

If you see signs like jobs drying up, being told "it's not worth having you on site now", or hints you should go self-employed to avoid "hassle":

• Start a written log of what's said and done (dates, who, what, where).
• Keep copies of messages and any written changes to shifts or contracts.
• Call Maternity Action or Acas and talk it through · they'll help you work out if it's starting to look like pregnancy discrimination and what to do next.

Agency and CIS workers

• If you're employed by an agency, the agency is responsible for maternity pay/leave; the site still owes you safe working conditions and risk assessments.
• If you're genuinely self-employed on CIS, you won't get SMP, but you still get:
  • Health and safety protection (the contractor has duties to you under H&S law).
  • Potential discrimination protection if you're really a "worker" and the reality is closer to employment.

In practice, many women in construction lean on Maternity Allowance and try to line up a return to work with trusted contractors, rather than relying on one employer doing the right thing.

What to do next

• Tell your employer in writing as early as you reasonably can · even a short email saying "I'm pregnant, my due date is [date]" triggers the risk assessment and discrimination protections.
• Ask for a pregnancy risk assessment · walk the site with your supervisor and flag height work, lifting, vibration, chemicals, PPE fit and shift patterns.
• Check whether you qualify for SMP or Maternity Allowance · use the GOV.UK calculator or call Maternity Action to work it out before you need it.
• If anything feels off · jobs drying up, hints about leaving, pressure to resign · start a written log and call Acas (0300 123 1100) or Maternity Action before you make any decisions.
