<prompt> Human: So my mum was the manager of the UK branch of a global chemical sales company that is being sold to another larger company. As such, the UK branch was one of the branches to be closed to save costs by the new owners. Shes worked for the same company for 17 years and will be redundant at the end of the month.luckily she got the same job at another chemical company last week and starts in January.However, the new owners of her old job have informed her that they will stop her working in the chemical industry forever.Is this legal? What are her options?EDIT: There is nothing in her contract stating she cant work for someone else  <response>: rlegaladvice
