Theresa May must guarantee funding to train new staff regardless of what happens after leaving the EU.
A new report by the Institute for Public Policy Research  suggests 55,000 care workers are EU nationals with an uncertain future in the UK.
In addition, the UK will need to recruit 1.6 million more health and social care workers by 2022.
GMB, the union for public sector workers, says Theresa May must pledge the necessary funding to train and recruit new care workers post Brexit – or the system faces complete collapse.
Rehana Azam, GMB National Secretary for Public Services, said:
"Our social care system is already teetering on the brink of collapse - and post Brexit there is the potential for it to topple over altogether.
"We desperately need well-trained, highly motivated care workers to help take care of our ageing population.
"If we lose tens of thousands of existing workers after leaving the EU the situation will become critical.
"Instead of holding hands with Donald Trump and refusing to publish details of her proposed Brexit plan, Theresa May must make a cast iron pledge to give our social care sector the financial backing it urgently needs - whatever happens after leaving the European union.
"She could start by agreeing to our demands to end the public sector pay squeeze."
