My new manager that took over the store I worked for wasn’t great at all. She agreed to look at a holiday request in advance, never got back to me then refused leave after I booked my holiday itinerary. She didn’t let me know in person, instead she messaged me on my day off quite abruptly. I tried to resolve this with her in an amicable way but refused to and came across as threatening. To the point where I couldn’t come in to work to serve my notice as I was very stressed, upset and uncomfortable. She then marked me as a do not rehire after I left. Ever since I’ve been trying to contact o2 hr department to provide evidence and let them know the situation as she left the company. I wanted to potentially resolve this and remove the marker so it doesn’t affect my ability to work for VMO2 in the future. But I was unable to get hold of anyone. I would appreciate it if I can contact someone to discuss this.
