Doesn’t pay too badly for the kind of work it is. Circa £28-£32k.
People don’t want to do it because the hours are long, and can be unsociable, and it involves working in a hot factory with flavourings and ingredients that frankly stink.
There’s no WFH, you have to be happy to stand up for 12hrs, and the work is repetitive and monotonous.
They are a staff of people like my mum who has worked there for 40 years, the occasional youngish lad, and Eastern Europeans.
They haven’t taken a job from hundreds of applicants, nobody applies.
