Unless a pregnant employee needs adjustments to working conditions for health and safety or pregnancy related reasons, you should treat them the same as any other employees.
The Equality and Human Rights Commission (EHRC) guidance offers simple do's and don'ts for employers to help them ensure they don't discriminate against those who are pregnant or on maternity leave.
For further information please visit the EHRC website.
The Health and Safety Executive’s (HSE) updated web pages explain how employers should manage the health and safety of new mothers and pregnant workers.
There is also separate advice for new and expectant mothers themselves and specific guidance on protecting pregnant workers during the pandemic and protecting new and expectant mothers at work.
