There's this lady at the restaurant I work at who refuses to communicate. She's a good cook from a technical standpoint, but horrible to work with because she is unwilling to talk. When she's assigned to do expo, she just throws the plates on the bar and doesn't keep them in order and won't communicate with the FOH and gets plates out of order so the FOH can't figure out which items are rare, medium, etc. and I usually have to step in and start running expo and get another cook to work the grill. However, that's just a mild annoyance compared to what she's started doing lately. Anywhere I've ever worked, it's protocol to say behind, on your back, permiso (when I worked with a lot of undocumented workers), etc when you're coming behind another cook, and especially if you're standing in their station's staging/expo area. Twice this week, she's been doing her own prep/outwork in my station's staging area with her headphones on in complete oblivion to anything else going on and without letting me know she was on my back and, when I turned around to plate some meat, she got lightly knicked by a hot spatula (no major burns, thankfully). All the other cooks there signal if they're coming behind someone, especially if they have to stay in or near someone else's station's staging area for an extended time (there's a mic over it, and sometimes other stations have to use the grill station's mic if theirs is backed up). I'm not territorial, so the problem isn't that she's in in the grill station, it's that she creeps up behind me and doesn't let anyone know she's back there and half of the time has her headphones in and is off in lala-land. To make matters worse, she takes zero responsibility for getting burned, saying that I'm just a dangerous cook and that I don't work safe. I understand that I ran into her, but to me, it's at least partially her fault for sneaking up on me and not saying "behind" or something of the like. Am I completely out of line for expecting her (or anyone really) to say "behind" when she's coming up on me, especially when she's worked for nearly 2 years at said restaurant and has at least 5 years of restaurant experience?
