I was worrking at a vet office forr 4 days i was in training to takke over for aomeone going on matt leave.after 4 days (16 hour) of training with no warrning and without the ok from the person who hired me (she was on vacation) they called and said they were going a different direction and don't feel i will work out in the long run.???This makes no sense i was only in training for a few days i did everything they asked of me i learned easily hwow to check in and out and invoice patients wwith no mistakes.i double checked any of my work with otheer staff and was reassured i was not doing anything wrong.so should they be giving me a reason why i would not work out?is it possible that one or two coworkers didn't like me and they fired me just for that?.and should they have the right to fire me if the person who hired me was not there for this decision?
