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.
