I wanted to reach out and get feedback on how to handle a situation with a new hire. I've been working at a restaurant as a line cook for several months now, recently our executive chef/owner hired a new line cook. Currently the new line cook has been working for about 2-3 weeks now and it's the first time she's worked in a restaurant for dinner service. She likes to talk A LOT, especially during prep time and anytime the executive chef comes into the kitchen. During service I work the grill, oven, plating and expediting food. She has sold tickets when I've turned around to pull items out of the oven and the orders where not ready to sell (therefore leading to food coming back to the kitchen and as an expediter I take the blame). I've talked to her and said I have to see all food before it gets sold, etc. Since she is new she isn't pulling meats to start cooking until the ticket is almost up to be sold and/or forgets items on the grill. I've tried to give her tips which I have learned, but she takes it as "talking to me like I'm stupid or I don't know how to cook (her words)." I'm a direct person and I don't raise my voice or anything. I myself am not a big chatter box during prep work, anyways she has taken my approach as a "I don't like you" type of scenario. Anyways, the other day during prep she got in my face and went on and on about her issues with me. She said some nasty things, blah blah blah. I let her go on and on. Anyways, she said some very negative and untruthful stories. Other employees where in the kitchen and were shocked by her actions. I spoke to my boss about it just to let him know what happened as a record. It has come to my attention by the new line cook that she has a extremely rocky past which has included physical violence, multi-million dollar theft ring with several years of incarceration and other issues. In addition she has begun spreading lies throughout the workplace with the foh staff and boh staff about me. I'm not there to make friends, for me it's a place to do what I love, grow and learn. Any advice on how to handle/deal with this? Greatly appreciated.
