The chief executive of Carers UK said that employers "can play a critical role" in changing how the society supports people with family responsibilities.
It comes at the charity announces an estimated 2.3 million have been forced to leave work to care for loved ones.
Helena Herklots said:
But support from employers can only go so far, and families need to be able to access reliable, good quality and affordable care and support services to enable them to juggle work and care.
Without urgent action from Government to ensure families can access this support, millions more will see their careers and earnings suffer - with long-term personal costs to families and significant costs to business and the UK economy.
An estimated 2.3 million people in the UK have given up their jobs to care for disabled, sick or elderly relatives and loved ones, a survey has found.
Less than a quarter of the population have seen their work affected by caring responsibilities, with almost three million people reducing their working hours to cope, an online poll for the charity Carers UK has revealed.
Out of the 2,073 adults Carers UK spoke to, the hardest hit were 45-54-year-olds, with nearly 30 per cent of them reporting that caring had taken a toll on their work.
The findings have prompted the organisation, along with the group Employers for Carers, to call for more support for people balancing work and caring roles.
