Mothertruck3r - Just out of interest, how many of your EU workers claim in-work benefits that you know of and is the tax and NI on their salary likely to be more than the total they get from in-work benefits, their cost to the NHS, their costs to state pension provision, cost to educate their children, cost on social services, pressure on housing etc?
Perhaps the reason you can't get any UK citizens to do the job is because they are not prepared to live in awful conditions in HMOs, cannot leave the country in a few years time with the money they have made in the UK and buy a very cheap house in their home country, aren't entitled to top up benefits etc.
In answer to your questions, I don't think hardly any of them claim any in work benefits. They all work hard. Not many of them have families over here and hardly any of them even use the NHS. They all like to travel back to their home countries for medical treatment. Hardly any of them even have a GP.
I also think that the living wage has had an impact. I can be paid living wage to work in a shop, a care home, with children, in a restaurant, as a cleaner, as an administrator, in a call centre etc etc. To be fair, working in a food factory is probably not going to be the first, second, or third choice for many.
The fundamental long term issue is however that we need people to produce food. If we pay people more to produce it, then we will pay more for it.
