I met Andy Burnham back in the early 90’s when he was Shadow Health Secretary. He visited the hospital I worked at and met some of the union reps, and I pointed out that all the professional staff who work in private healthcare were trained within the NHS at taxpayers’ expense, and shouldn’t the private sector be paying some of that back? He promised to look into it, and 30 years and 2 Labour administrations later I’m still waiting.
Things are slightly different sector to sector, but in a lot of industries, if an employer funds your training for a professional qualification, they usually expect at least two years post graduate work or you pay an element of the training cost back(new employers often end up paying on the employees behalf).
Surprised the NHS has nothing similar
