About 150 employees have signed up to the service, which is provided by My Family Care and includes emergency childcare, school holiday cover, and elder and adult care.
Childcare support is in the form of childminders, nannies and nursery places. The company funds six sessions of care for each employee annually.
Cara Collins, vice-president, senior employee resources consultant at Northern Trust, says: “In our focus on employee engagement, it is our aim to have a workforce that is motivated, productive and energised.
“We hope that by supporting our employees through stressful situations like childcare emergencies it will help them better manage the balance between work and life, and have a positive impact on their engagement.”
