From the petition:
In 2011 and 2013 HMRC investigated the care sector and found that only half of care providers were paying the national minimum wage. Thanks to their investigation several companies were forced to pay care workers the money that they were legally owed.
Now, because of the ongoing cuts to care budgets and a lack of follow up action from HMRC the situation has become worse and now 220,000 care workers across the UK are being illegally paid.

Surely underpayment on this scale is essentially equivalent to the care sector unilaterally deciding that, fuck the law, they're just going to ignore the minimum wage? And if they can get away with it, then how many other employers will start thinking they can too?
