Obviously, all workers deserve overall protection. Many workers have additional forms of collective bargaining or representation through different structures. Agricultural workers in some areas are an example of an extremely fragmented and isolated group of workers; in other areas, there are big concentrations for small periods of time. The work is seasonal and there is insecurity.
The issues they have experienced over many years are well-documented. I think that singles them out to require more than the basic national minimum wage, working time regulations etc., to take account of the fact that people may have accommodation tied to their role, which could be their permanent home or temporary accommodation for a seasonal role, or that transport could be provided, which, in extreme circumstances, is used to keep people on site beyond the time that they should be there or is denied to them. Those kinds of things mean that there is intense pressure.
