@megletthesecond easier for the farmers to employ and exploit many Eastern European workers No need to worry about those pesky workers rights for those guys!
See my previous post. It is 100 years since seasonal agricultural work was done by British workers. Farmers have been exploiting seasonal workers for centuries - but since the end of WW2, people have had the mobility to move elsewhere for other work which is better paid and less backbreaking. As for workers rights - these are supposed to be controlled by the UK government agencies such as the Border Force and HMRC. If gangmasters are paying less than minimum wage, they should be prosecuted.

The farmers should be changing their expectations. 5 days a week for people, shift work kind of thing, just don't have them working weekends at all.
Crops need to be picked when they are ripe and ready - regardless of whether we're talking about raspberries, rapeseed or wheat. Crops grown for the supermarkets - salad, soft fruits etc - need to be harvested to meet the demand from the supermarkets, whose demand can change by the day depending on the weather, Bank Holidays etc. If a field has to be harvested within an 18-hour timeslot, either the work gets done or the crop rots.
