Ouch! That's just...beyond awful!
That temp really had no right to say anything to anybody, especially someone who was working their permanently and not just for a few days. I've done a bit of temp work myself and never thought it was my place to correct anyone who worked there permanently. That's what the management is for.
I also got the "catch on immediately" treatment quite frequently in jobs. I usually ended up quitting those jobs just because it got so nasty and became so stressful, I wasn't going to waste my time getting abused like that by managers and co-workers for being new. I know that's not an option for poor Iruka, but I know how that sort of crap feels.
First job I ever had, I was still in college, and only worked at the place on weekends so I could focus on my schooling during the week. Since it was weekends and not daily, I was obviously not going to catch on as quickly as another, and definitely not in a few days. The place I worked at was a gas station with a VERY complicated system of ringing items up that involved a code for one group of products or another, plus I had to remember what items were "taxable" and what weren't and that distinction wasn't made clear either.
Most of my co-workers were decent, but a couple of them treated me like I was just a stupid college kid who was only there on the weekends instead of wanting to get a "real" job. I got reamed for not catching on quickly enough, too, even though I'd only been there three days over the course of two weekends and hadn't been shown everything. One gal actually thought I knew how to open the security alarm(I worked mornings) and was "shocked" that I hadn't been shown when my own manager had told me that it was too early for that. Yikes.
Something I did that might help Iruka was I kept a notebook. I couldn't keep half the codes and "taxable" items straight, so I brought a notebook and wrote it all down, adding new things as I learned them, so if I forgot(particularly at lunch when I had a store FULL of customers and absolutely NO help) or was in a hurry, I could quick look instead of having to ask someone or find my manager.
Maybe she can try that to help or something, but those people there shouldn't be treating her like that because you're right, it IS only her 3rd day or so. Her co-workers have probably been doing the job for MONTHS, if not years. They can't expect her to "magically" learn overnight. They were new once, too, but it sounds like they forgot what it was like. *shakes head*
*HUGS* To you guys. Hope things get better for you 'n Iruka!
