A new study by instantprint has revealed the extent of Britain’s summer sickie culture, with childcare costs emerging as an unexpected driver behind workplace absences.

Surveying 2,000 UK office workers, the research found that 43% admit they have pulled a summer sickie, while almost a third (31%) of working parents say they have used a sick day to manage childcare challenges.

The findings suggest that while sunshine still tempts workers away from their desks, rising childcare costs and mounting family pressures are creating a new set of challenges for working parents during the summer months.

According to Pregnant Then Screwed’s State of the Nation Childcare Report, 45.9% of parents have gone into debt or dipped into savings to pay for childcare, while 53% spend more than a quarter of their household income on childcare costs.

Meanwhile, Coram’s annual Childcare Survey shows that the cost of a full-time nursery place for a child under two exceeds £15,000 per year in some parts of England, with additional holiday club and wraparound care costs adding further pressure during school holidays.

Against this backdrop, instantprint’s research found that 48% of parents describe summer childcare costs as financially stressful, while 41% worry about how they will cover childcare arrangements throughout the six-week summer break.

The research also highlights the growing role grandparents are playing in helping families stay in work.

Recent comments from actress and mum-of-three Helen Flanagan, who spoke openly about relying on her parents for support with childcare and family life, appear to reflect a much wider national trend.

According to the survey, 62% of working parents rely on grandparents or relatives for childcare support at least once a month, while 29% say they could not maintain their current working hours without help from family members.

Among parents without access to regular family support, 47% say school holidays are the most financially stressful period of the year, compared to 31% of those who receive help from relatives.

While childcare pressures are shaping workplace behaviour, Britain’s relationship with sunshine remains strong.

The survey found that:

• 27% have called in sick because the weather was too good to miss
• 54% feel less motivated to work during periods of hot weather
• 39% struggle to concentrate during heatwaves
• 22% believe colleagues regularly fake sick days when the weather is particularly good

Workers were also asked what they believed were the most common excuses used to justify a summer sickie.

The top responses included:

• Stomach bugs (42%)
• Migraines and headaches (38%)
• Food poisoning (34%)
• Flu-like symptoms (31%)
• Childcare emergencies (28%)
• Caring for a sick family member (24%)

The findings point to a wider shift in workplace expectations, with flexibility increasingly seen as a solution.

More than half (58%) of workers say flexible working arrangements reduce their temptation to call in sick unnecessarily, while 63% believe greater flexibility during the summer months improves both morale and productivity.

Vicki Russell, Head of TX at instantprint, commented:

“While the idea of a summer sickie often raises a smile, our findings suggest there are some serious challenges sitting behind workplace absences, particularly for working parents during school holidays.

“Childcare costs continue to place huge pressure on families, and many employees are juggling work commitments alongside increasingly complex childcare arrangements.

“What stands out from the research is the positive role flexibility can play. When people feel trusted and supported, they’re often better able to balance work and family responsibilities without feeling forced into difficult choices.”

She continues:

“Grandparents are clearly playing a vital role for many working families, but not everyone has access to that support network. As organisations continue to evolve their approach to flexible working, understanding the pressures employees face outside of work will become increasingly important.”

The findings highlight how Britain’s famous summer sickie culture may be evolving from a light-hearted workplace tradition into a reflection of wider financial and family pressures facing employees across the UK.
