Yeah, you can try to apply for any internal "vacant duties" available in the Mail Centre you work. "Try" is a good word, because Royal Mail HR will tell you that you cannot
apply, as the internal jobs are for the Royal Mail staff only. Then have a look at the Agency Workers Regulations 2010, Regulation 13, after that, read this:https://assets.publishing.service.gov.u ... _Final.pdf
or check employment Tribunal decisions, case number: 1805244/2018
in this, read paragraph 6, Complaint 3 (Royal Mail being found in breach of the law, for refusing Angard agency workers to apply for internal vacant "duties", in Leeds Mail Centre)
get yourself a lawyer or do it yourself, and take "Royal Mail Group Limited" to your nearest employment tribunal, for some handsome compensation, for not being allowed to apply for the internal jobs at your local Royal Mail Mail Centre. Simples! Royal Mail are going to claim that these "vacant duties" are not really "jobs", but no sane ET judge will buy this explanation. These "internal vacant duties" are nothing but "JOBS". Vacant duties = vacant posts = vacant jobs. Thank you, please.
