<prompt> Human: I am 19 years old, I am a part time employee at a grocery store. This grocery store is in a union. I am a department head who runs the front end. Since i am a part time employee, i am required to have one day off during the week excluding Sunday. So, i am enjoying my day off, and i get a phone call saying that an employee has not come in for her shift, and has not called in beforehand. No contact is being established with this employee. Since the store desperately needs me to come into work and close the store, i do. I worked for 5 hours, not much. But i believe this 5 hours is considered over time. So my pay should be time and a half. Now, here is my problem. I was told that since i worked over time, some of the managers might take away one of my shifts so i will not get overtime pay. I will probably lose hours in the process. So this is the billion dollar company saying to me that they will not pay me extra money for the loyal work that i did for them. Can i fight this in any way? I believe since i was scheduled for those hours, i should still get to work those hours. Plus since i worked on my day off and saved their behind, i should get overtime pay for it. Are companies allowed to take hours away in this type of situation? I will settle if i get what i worked for. I would love to get even a dollar pay increase to my rate. If anything, i wish they would pay for my student loans. But i am not greedy enough to ask for something like that, only dream of such things. In the end, do i have a claim, or should i speak to someone professional?Please, anyone with any info or experience please respond to me so i can see how to respectfully approach this situation. Thanks.  <response>: I dont know what grocery store you work at and the unions rules or anything, but in general, this doesnt seem to have any issues.Sometimes things come up and the planned schedule has to be changed. You had to work a day you werent supposed to, so they took you off for a different day. That is just the way it works sometimes. it seems that if they would have left you on the regular schedule the extra 5 hours, that would have been an issue.
