<prompt> Human: Hey was wondering if anyone could help me out? Ive been working at a company for 2 years now and Ive been paid a flat rate of 6.90 an hour, irregardless of it being a night shift, weekend or bank holiday.It recently came to my attention that at another company establishment, no more then 15 mins away the people there that do the same job like identical at the same position are somehow paid 2.50 more found this out through a job advertised there. So thats the starting rate!Now without wanting to sound greedyjealous this understandably got my back up a little bit and upon asking my manager about it I just got brushed off with thats how life isIm wanting to take a stronger approach for myself and my 3 colleagues to at least secure some small pay rise or some form of night premium to at least compensate us for the unsocialable hours and the health risks alternate shifts give if the recent BBC article is to be believedI was just wondering how exactly I would go about doing this, or at least getting some forms of motionETA: I cant change the title! I mean night premium not premonition oopsETA2: The other establishment is same company, same area, same job and industry worked. Like its literally my job just transplanted into a different buiding.  <response>: Whatever you do, definitely do NOT use the word irregardless in any professional setting... or ever really.
