I had my annual review. At the bottom of the review it has future goals. My goals were to keep doing what I have been doing. I am rotting in this job but, the pay is OK. The next day I went to my manager and asked if she could perhaps create a supervisory position in our department and that after 8 years with the company, I felt I was ready to fill this position. She actually yelled at me. She slams her hand on her desk and says "DO YOU WANT MY JOB?, HUH, DO YOU?" I was stunned to say the least. That made any doubt in my mind that this was not a thankless, dead-end job to rest. Heck, I just had to go to the owner of the company to get a key to the closet where paper towels are kept. My manager wants me to ask her when I need to get in there, I can't anymore. When I think about these things, and there are many, many more, I feel like a little kid. You see, other people have this key so they can get paper towels but my boss doesn't want any of her people to have one. We all look like a bunch of chumps, asking permission to dry our hands off. Anyway, Friday I went to see a house. (The owner of the company rents to me so I sort of have all of my eggs in one basket, I can't live there and work at another company and the housing here is crazy priced. Homes start in my area at 700K.) Anyway, I went to West Virginia, I found a farmette on 2.5 acres an older couple is selling very cheap. On flat land, mountain view, huge garden with grapes, blue berries, peach trees apple trees, I can go on forever. I am nervous about this change but what I am doing now in my job is driving me crazy and I am not happy at all.
I just had to get this off my chest. Does anyone know anything about chicken farming? The man said he would leave the 47 chickens if I wanted them. They have an automatic feeder and waterer. I have no idea whatsoever about how to care for chickens. I can't chop off their heads so don't suggest that. They are the egg laying kind but he said I have too many roosters, about 20 too many. Am I doing something crazy? I am so unsure of myself after being in this job for so long. I need to get my confidence back. My kids are 50/50 on this. Can a 40 year old widowed female pull this off???
