The policy will allow employees pursuing fertility treatment to have 16 days off in a 12-month period.

Partners and individuals supporting those having treatment will be eligible for two days in paid leave under the scheme.

Anyone going through pregnancy loss will be given up to four weeks’ paid leave, with paid time off to allow them to attend any related medical appointments.

The pregnancy loss policy will also apply to partners and surrogates.

Paid leave will be open to all employees regardless of their length of service.

Flexible working, reasonable adjustments including extending blended working arrangements, temporarily changing or reducing working hours, phased return to work plans, occupational health assessments and access to quiet or first aid rooms will also be supported by Ipsos.

Ipsos said it would provide managers with access to information and guidance to help individuals experiencing pregnancy loss or fertility treatment.

Employees will also be able to access support provisions such as guidance on talking to line managers, a wellness action plan, mental health first aiders, financial coaching, employee assistance helplines, signposts to external resources and flexibility in how they use any time off.

Ipsos has signed the Miscarriage Association’s pregnancy loss pledge and also consulted the association when drawing up its new policy.

The new policy follows Ipsos’ decision to introduce a similar scheme for the menopause last year.

Claire Timmins, HR director at Ipsos, said: “Ipsos is fully committed to supporting its employees and these policies are another important step in helping everyone feel part of an inclusive work culture.

“We have always supported our people, but we hope this policy breaks the associated taboos, while also raising awareness and understanding of the impact of pregnancy loss. Thereby creating an environment where those affected feel safe and supported in talking about their loss and their needs.”
