I'm returning to work soon after taking 12 months maternity. It appears that my employer may add more duties to my job which are currently out of the scope of my job specification. These duties will be in addition to what I was previously doing and there will not be any recognition (extra salary). I was wondering what my rights are with regards to this? The extra duties are from a recent redundant position. My position previously was not great as I was carrying out duties for 2 positions.
