People who lost their jobs due to the collapse of Carillion are still seeking justice 600 days after the engineering giant was forced into compulsory liquidation.
Unite, the 海角视频 and Ireland's largest union, has criticised the government for a "business as normal approach" amid what it described as "continued inaction" against the company's directors and senior managers.
The union has stepped up calls for a "root and branch reform" of company law, with Friday set to mark 600 days since Carillion, which was headquartered in Wolverhampton, went out of business, Press Association reports.
Thousands of workers lost their jobs, with Unite now taking employment tribunal cases for around 220 former employees, claiming a lack of consultation before they were made redundant.
The union said Carillion's two flagship hospital projects, the Royal Liverpool Hospital and the Midland Metropolitan Hospital, are years behind schedule with work not yet restarted or only just getting under way.
The Royal Liverpool Hospital was originally due to be completed by March 2017 but work has only recently restarted.
The Midland Metropolitan Hospital near Birmingham was due to be completed last October but will not be finished before late 2021, Unite said.
Unite assistant general secretary Gail Cartmail said: "As we approach 600 days since the collapse of Carillion it is totally apparent the Government has failed to learn any lessons from this debacle.
