Undercover Boss

At just 42, Stephen Martin was recently appointed chief executive of the Clugston Group, a major force in construction, building roads, schools and supermarkets.

But the industry is in crisis as a result of the recession - hundreds of companies have folded and nearly 30,000 construction workers have lost their jobs.

So Stephen has decided to trade in his suit and expense account for a hard hat and a canteen lunch and, armed with a cover story, he visits his construction sites to work alongside his frontline employees.

He pours concrete, works in blast-furnaces, tries his hand at carpentry and does freezing night-shifts repairing roads, while searching for the best way to run the business.

He confronts the consequences of his executive decisions and hears exactly what the workforce thinks of the management.

After two weeks on the frontline, he'll reveal his true identity to his staff - and introduce some major changes.
