The poll of 3,000 working mums and dads of children up to the age of 11 highlights the struggles they face with juggling work and childcare.
Carried out for the charity Working Families ahead of National Work Life Week (7-11 October), it reveals:
31 per cent have requested flexible working arrangements to balance their responsibilities.
16 per cent claim the impact of accessing childcare has led to them avoiding applying for new roles.
75 per cent regularly work overtime as 23 per cent claim it's the only way to manage their workload.
Nearly three in 10 (28 per cent) are implementing variable hours, 19 per cent are remote, and 15 per cent work term-time hours only to help with childcare issues.
A fifth of parents don't have any flexible arrangements in place - with this being most prominent in the transport and logistics sector (42 per cent).
Despite 62 per cent claiming their employer cares about their work life balance, 51 per cent have previously refrained from applying for a job because it didn't offer flexibility.
Six in 10 work shifts, with 27 per cent receiving up to only one weeks' notice of their schedule - making it difficult to organise childcare arrangements.
Jane van Zyl, chief executive of Working Families, said, 'Accessing affordable and reliable childcare has become a significant challenge for many families.
'A lot of parents are struggling to balance work and family life due to limited availability, rising costs, and long waiting lists.
'It's not just an inconvenience - it's a barrier that impacts career opportunities, financial stability, and overall well-being.'
