The price of hiring skilled workers will continue to rise unless employers invest more in training, the leader of one of the country's biggest trade unions has warned.

Derek Simpson, joint general secretary of Amicus, said employer groups should stop "whinging"

about the cost of measures to tackle the country's skills shortages.

He said the Government was trying to reverse 20 years of underinvestment in skills.

He said: "Employers have brought the situation on themselves by failing to invest for so long."
