Input:  I'm a university student with a part-time job working at a shoe store, which I've had for two years now. It's not a big store - there is one manager and six employees. One of the other employees, Sarah, goes to the same university as me. She's a bit of a loud, gregarious sort of person and a bit of a party girl, while I'm pretty quiet and reserved. I spend a fair bit of time listening to her stories/gossip about going out on weekends, but otherwise we get on fairly well.

This past Saturday Sarah was scheduled to open the store at 9 a.m. and work to 5 p.m. (close) and then I was initially scheduled to work from 12 p.m. to 5 p.m. On Friday, for some reason my manager asked me to start at 9 on Saturday too. It was a long weekend where I am (Family Day), so perhaps he thought it was going to be busier.

I got there around quarter to and started to open the store. Sarah arrived around 9 and was surprised that I was there. She had clearly been out the night before and said that she was pretty hungover. However, after a little while it started to become clear she was more than just hungover - she was still pretty drunk. She was a bit unsteady on her feet (albeit, wearing heels), giggly etc. I'm not great at confrontation, so I mostly just left her at the desk and helped the very few customers we had. She told me it was her friend's birthday and they had all drunk far more than they usually would. It was an annoying morning, because I had to do everything on my own, plus make sure she didn't do anything stupid. Later on, she was clearly not feeling well and I told her she should go home sick and I'd finish the day on my own.

Before close, my manager stopped in unexpectedly. When he stopped in he asked where Sarah was and caught me offguard. I was still feeling pretty annoyed at her, so I just sort of blurted out that she had a rough hangover and went home sick. He followed up asking if she had been there to open the store on time, and been working. I gave a sort of wishy-washy answer, and I think he could tell I wasn't being completely honest, so he persisted. I ended up telling him that it seemed she was still kind of drunk that morning. He didn't really say anything other than that he'd have to talk to her about it.

I've now found out that he let her go when they met this week. I feel awful that she's now lost a decent paying job, which I know she needed to help pay for schooling. My roommates think I should have just covered for her as a fellow university student. I know it was her own decisions that led to this, but I also think if the scenario was reversed, she would have covered for me, which leaves me feeling a bit like a tattletale of sorts. And from her perspective, I told her she could go home and I would cover for her, then told our manager all about it, she lost her job, and now I'm going to get some of her (better) shifts.

Thoughts?
