A research report from Citizens Advice Sheffield has highlighted deteriorating employment practices that are impacting on Sheffield workers rights and pay. The research highlighted the growth of zero hours contracts and self-employment arrangements and calls for action to improve employment rights and remedies to unfair practices. The researchers estimate £2.7 billion is lost nationally each year in wages withheld from people who are legally entitled to them. Sheffield Live! reporter Azz Mohammed spoke to Tim Arnold of Citizens Advice Sheffield.
