<prompt> Human: So the hospital I work for increased the rate of Call for our nurses from 10 to 12 per their union negations and it was announced that the Surgical Techs would be receiving an increase as well back in July. Great. Except only the Certified Techs have received this increase.When I asked my manager to check into it with HR they said that since the union we are NON union that negotiates call pay for similar positions didnt bargain for higher call they would not be increasing ours even though the certified techs all received an increase so I am four dollars behind the certified techs.This is very frustrating for me as I have been taking a ton of call recently thinking they were going to cut me a Retro check at some point.I was trained on the job as opposed to going to school so I am unable to become certified for another month as you need three years experience.I dont really know how to proceed. I love my job but this just seems really unfair to the people like myself that are trained on the job and cant certify until a set amount of time has passed.  <response>: The other techs either put their time into school or in field work to become certified. They should be making more money. In a month youll be able to become certified as well and you should start looking for a new skill to become certified in. Im sure you wouldnt want to be paid the same as an uncertified new hire once youre certified.
