Family wellbeing is becoming one of the strongest determinants of whether an international assignment succeeds – yet employers are still struggling to provide consistent support, according to AXA Global Healthcare’s 2025 World of Work report.

Now in its third edition, the study has found that pressures on family life are among the most common reasons for assignments ending early. While most employers offer core practical help such as relocation, healthcare access, and visa sponsorship, structured emotional and personal support for families is far less common.

Only 38% of families receive universal support, 28% get it on a case-by-case basis and 24% only after a minimum tenure. Even when benefits such as extended leave or paid trips home are available, just 40% of assignees know they exist – pointing to a significant communication gap.

The impact on wellbeing is substantial. Assignees who relocate with partners or children report far better mental health outcomes (67%) than those living apart (42%) or moving alone (48%). Yet families continue to face obstacles: 35% say partners struggle to find work, 31% report strain on family life, and 28% say their partner or family would prefer to return home.

For those whose families remain in their home country, distance takes a toll despite digital connectivity. More than a third say their wellbeing has suffered, 46% report strained relationships, and over a quarter have experienced worsened physical health. Only 29% of employers allow flexibility to adapt benefits to cover partners or families.

“International placements are about people – not just roles, budgets, or business strategy,” said Karim Idilby, Chief Growth Officer at AXA Health International. “When families are supported to settle, stay connected, and feel well, assignees thrive.”

Repatriation still a major gap

The report also highlights weaknesses in support when employees return home. Although many receive a promotion or guaranteed role, personal wellbeing and cultural readjustment remain challenging. Only two in five assignees are offered psychological support after returning, despite nine in 10 experiencing mind health challenges during their assignment.

“Coming home can be the hardest part,” said Virginie Faucon, Chief Marketing Officer at AXA Health International. “The adjustment can be unexpectedly complex … Yet only three in five HR decision-makers provide reverse culture shock training.”

A shift in what defines assignment success

AXA’s research suggests that while salary and logistics remain important, wellbeing, cultural integration, and family inclusion are now central to sustainable mobility strategies.

“Successful international placements build resilient, global organisations,” added Idilby. “But that success depends on people’s lives, families, and wellbeing being supported … Repatriation needs just as much support as the move itself.”
