Yesterday, I was asked if I wanted to work today. I asked what exactly I would be doing. I was told basically pushing back to school. Instead, when I got there this morning, I was given a list of 5 sales planner for hba. I am a newbie at this. The sales planner labels had to be printed. I don't know how to do this. A tm was kind enough to help me. The computer in the training room wasn't printing them, neither was the tsc computer. 2 hours of my 7 1/2 hr shift wasted. I had to use a portable printer to print the labels. The portable printer at times would go offline and would not even print all the labels. I was so stressed. Anything but hba. I rather do b, c, d or e. Hba has so many items to move into the home location/backstock/pull and shippers. I completed 3 of 5. The other 2 included shippers that had to be mounted to both sides. I told the stl I didn't understand those 2, she told me to flex them. This other tm told me if the shippers are not available, I wouldn't be able to do them. The thing is, I went home with a massive headache. I should have said no to coming in today. The stl seemed to be clueless. Just had to get it out.
