After a bit of advise please from the all knowing GD 
I've just been informed by colleague at work that he's earning about 2.5k per annum more than me, even though we both started at the same time and do the same job.
He thinks I should raise this with our Manager, should I? Would you? If so, how would you approach the situation?
