2018 Year of staff shortages in UK seasonal sectors or not !!??

As 2018 starts i understand from colleagues who work closely with labour providers that already the year has a different feel to it than previous ones, as the previous pool of talent from outside the UK seems to be reducing. At first this might seem a worry to the sector, as if the trend was replicated then it could be trouble ahead, however the very same report that part of the decline in numbers to work in agriculture or packing houses, is that those individuals are themselves seeking to upskill and so if Leisure offers an attractive proposition then it might actually not see the same squeeze on labour as some other sectors are already reporting.
