I used to work at ihop in Reynoldsburg ohio and i was just fired for a very dumb reason, i had just finished high school and had my graduation party set on a Specific day and there are * managers at that restaurant. I told * out of the * multiple times that i was not going to be able to work the **th or **th of this month and had one write it down on her scheduling note book and i wrote it down on a sticky note and put it in their office but now one of the managers i told is pretending she doesn’t remember me telling her multiple times starting * weeks ago that i couldnt work and at the time the two managers were fully aware and said i did not have to come. But the * rd manager fired me said that i was scheduled to come in and i had no right to take * days off work. I asked for the manager’s boss’s number but they havent replied to me and its been ** minutes. Please call back so i can get this situation fixed properly
