Yup. Twice.
Once, I was supposed to start a job working in an area that I had experience in and was comfortable doing the tasks. When I got there, it was the busiest day of the week, and the owner was frazzled. He pretty much threw me what I needed to work with, and said "take that person over there". No tour, no orientation, and no working in the area/tasks I was familiar with. It was kind of a front of the shop/back of the shop situation, and I had always done the back of the shop. I had no idea where anything was, I broke something trying to adjust it, the owner found a new one and while fixing it, said "I'm going to kill you!" He meant it to be funny, but I sure as heck didn't take it that way! I finished out my shift and got in the car knowing I was never going to go back there again! And since the owner never had me fill out any real paperwork, all he had was my phone #. He called the next day when I didn't show up, and my roommate told him that nobody by that name lived there LOL I was like 22 or something. I never did get paid for those 4 hours, but I didn't care! It was awful.
The 2nd time, I worked at s small daycare/preschool in my little town. The owner of the school was bi-polar and had ADHD, so one day she was nice and sweet, then all the sudden the next she would turn on you and go crazy. She was like that with the kids, too, on occassion. She didn't want to work, so she had her staff run the place, which was fine with us. It was much easier to work there without her around! I was allowed to bring my kids with me, for free, and at first it was just DS1, then I had DD while I worked there, and then 19 months later had DS2. By then, DS1 was already in school and just came back to the daycare for PM aftercare. Then summer hit, and enrollment was down because of the economy in our state, everyone was getting laid off and didn't need daycare. Ms. Owner was getting scared and (I believe) rethinking her long-standing decision to have staff kids attend free. I ran the summer camp for the older kids, so I had DS1 with me pretty much all the time, DD was 2 and potty trained, so when we were outside or attendance was low, she would come to me, which was fine, but then, the owner decided she was going to work more to cut down on payroll, and thought that the baby room would be the easiest. DS2 was about 4 months old. He was a good baby, but the director also had just had a baby and she was there as well. So, she would constantly tell me to bring DS2 with me into the school-age summer camp area and keep an eye on him, just for a while. I was fine with that because I didn't really want her taking care of him anyway, and my 5th/6th grade girls LOVED to help me with the baby. (even though it was totally against state guidelines)
Anyway, I could feel the tides turning, and I was going from being a "star teacher" to a problem for the owner. I wasn't the first one...I witnessed her turning against employees many times over the 5 years I was there. I always knew it was possible. She started to lie to me, and avoid me. The last straw was when she was talking and DS, who was 6 at the time, said something to her and she whipped around and literally screamed at him. He was a good kid who she always liked, and he didn't say anything bad....she was talking about what the school age kids were going to do that week and he piped in with a suggestion, like all the kids were doing. Nothing rude, nothing snotty, not even anything crazy. Just a suggestion of walking to the park or ice cream store. She totally lit into him telling him that it was HER school and she didn't need him telling her how to run it, etc, etc. The other teacher and I were stunned for a minute, then the other teacher took DS out of the room, and Owner and I had a little chat. I told her that if she didn't want me working there anymore, I was fine with that, but she will NEVER talk to DS like that again because he loved her and looked up to her and did NOT deserve to be yelled at, and if she ever had a problem with him again, she needs to bring it up with ME.
She apologized, but also said that she heard I said something to the director and she was mad about it. So instead of asking me to explain, which I did and it was a total misunderstanding in the first place, she decided to just be snotty and mean. It never really got better after that, and I formed a plan to make my exit. After 5 year and 3 kids, we had a LOT of stuff at the school - clothes, bedding, diapers, bottles, cups, extra formula, all of my teacher supplies...just a whole lot of stuff. I knew once I gave notice, I would not be allowed back, so I started packing up on a Monday, and took everything home little by little. I actually closed the school on the last day, so the last thing I did was take down all of my kids' name tags and labels off of everything before I locked up. I left my keys, school-issued phone, and resignation letter on the owner's desk as I walked out. We never went back.
Best decision EVER.
