Hi, due to some changes within the team the lead has left and three new guys on 15k more than me are now my juniors. They were brought in from a smaller contract where they were team members they are just older an hence have higher salaries. I am however their senior in every job related way. Unfortunately we are all the same gender so it seems I cannot claim the equal pay act to try gain a pay rise. Is there any other laws that I can use to stop me getting taken advantage of?
