These were jobs filled by workers from the EU, but Brexit and the pandemic mean a lot will have returned home. Brits aren't prepared to do those jobs for those wages.
We've never had a problem filling our warehouse positions at work from Brits until 2021 where it seems to have taken a massive slump with few prepared to do the job.
We have a massive problem at the moment as since 2021 for some reason most applicants are just woefully poor quality and the small number of good ones increasingly seem to want specific conditions, etc. which don't fit with the job and/or they'll agree with the requirements but then once offered the job turn around and say they can't work specific days or patterns that they said wasn't a problem at the interview and so on. It makes quite a difference from a few years ago where we'd have like 400 applicants for one position and able to cherry pick.
I'm getting a bit fed up to be honest of the number of people who can't at the very least do the basic job to a reasonable standard - I can understand not being motivated to do any extra, etc. but the number of people who just don't care, even if it makes extra work for other people or causes health and safety situations, etc. and are lazy as **** just isn't acceptable.
