Clearly time and money is being wasted on London Underground and other public sector services. However this is not the only industry to be plagued by work-shy ground level staff. Any workforce arrangement requires good management. Poor management breeds poor workers. How long will it be before we suffer massive loss of life?
Ben, London

An excellent documentary highlighting the problems within the underground system. And look now at what has happened. You have highlighted an infrastructure Paul which was about to crack and what must you be thinking now.
Roderick Swaine, Blackpool

Can you imagine how horrible that job must be? Steve Thompson, UK

The 'gaffer' is in charge of five men, not 22 as you stated. And he is told which underground station to go to and what work to do, it is not his choice. I think it is terrible that these men are being blamed for something they have no control over.
Saffron, Canterbury

The lack of supervision by management should be investigated and also the men filmed should be sacked immediately. Could the crash a few days later have been caused by bad maintenance? I shall certainly think twice before risking my life on the Underground system in future.
Ann Bianchi, Dorchester

I am disgusted. These people you filmed are on camera and the evidence is clear to see. They should be sacked. No question about it. London Underground needs a shake up and heads should roll over this fiasco.
Fiona Blakelock, London

Do you work hard in your office every day? Do you sometimes have days when you hardly get anything done? Do you need to have two jobs? Is it the worker's fault or a management issue? Can you imagine how horrible that job must be? Believe me, it is not something you would want to do. It is hard, noisy, very unsafe and appallingly paid.
Steve Thompson, UK

Since you have painstakingly uncovered the taxpayer's money wasted on tube maintenance, I hope that future shows will see Paul Kenyon investigating the BBC's squandering of licence fee payers' money on digital channels no-one watches, endless billboard hoardings and merchandising.
Jim Backhouse, London

I hope they do something before someone gets killed Louise, Hampshire

I feel there should be an enquiry. I thought it was disgusting the work did not get done for so long. I do not feel they should get away with it. I am not very pleased at all how our taxes are being spent. The workmen thought it was a joke. Well I do not. I will not feel very safe using them the tube in future. I am going to write my MP about this.
Mrs George, Lincoln

I cannot believe they have got away with this on the underground for so long. All sub-contracting should be stopped. If jobs overrun, the workers should have to account for it, just like workers in every other industry. It is our money they are wasting. This has got to stop.
Mic Riddy, Worthing

I am horrified and alarmed by these discoveries of dodgy working practices and appalled by the response you got in the statement from London Underground. The state of our public transport system is a scandal and I feel extremely pessimistic about seeing any improvement.
Maxwell Clarke, London

To pick a group of 22 men out of millions to portray your views on the damage PPP is inflicting on public services is totally unacceptable. Perhaps Mr Kenyon's next assignment should be undercover at the BBC, examining the millions of pounds being spent on the luxurious refurbishment of BBC properties, at the licence payers expense.
Andy Burgess, Essex

These matters need urgent investigation Sarah Smith, London

I believe the programme was harsh to pick on individuals in the manner in which it did. The London Underground workers that were filmed probably have families to support and mortgages to pay. Now they will probably lose their jobs. The taxpayer will now have to dig deeper into his pockets to support the underground workers you have made unemployed.
Steven Dent, Rochdale

My boyfriend regularly has to go and work in the underground. His stories of delays, nights of getting nothing done, protection masters not turning up or falling asleep are awful. On the face of it LU are all safety and rules, on the ground they couldn't care less. I hope they do something before someone gets killed.
Louise, Hampshire

I was glued to the programme in absolute horror. I have written to the Mayor and will also send my comments to the Department of Transport. These matters need urgent investigation. You have done the work. We now need action.
Sarah Smith, London

It is outrageous to repeat the mistakes of the railways Anna Langley, London

Superb undercover work. This issue should be of huge concern to taxpayers & Londoners. Who is steering the ship that is the underground's future? And will this board remain in existence long enough to see their 'plans' through to fruition?
Dominic, Reading

Thank you for displaying the attitude that destroyed the UK's manufacturing base. I am a company owner with hard working staff, who I value even more as a result of this programme.
Brian Calo, Swansea

This is shocking. It confirms all our fears about how our public services are run.
Richard King, London

I was sickened by Mr Kenyon's report into the Underground and its appalling management practices. Surely this represents criminal negligence on the Underground's behalf? Not only should the Government act, but the police should also be brought in.
Gavin Marshall, London

I was enraged watching this. Both over the waste of money and how we have been stitched up over PPP. It is outrageous to repeat the mistakes of the railways.
Anna Langley, London, UK

This was a piece of arrogant, poorly researched, self-important twaddle. You completely missed the point about PPP as it impacts on the Underground. And the scene where you demanded an interview with the LU Chairman on turning up in reception was cheap, dated showboating. What would happen if you turned up at BBC TV Centre unannounced, demanding to see your chairman?
Neil Howard, London

Whilst your programme picked up on the work-shy and self interested attitudes of the individual gangs, it was misguided in criticising PPP. Once FTSE listed PLCs get their hands on maintenance contracts these practices will end. It was also misleading to show the letter exempting contractors from a Green Card, as it was clearly in relation to cleaners who have no track access certification.
Mike, London
