My worst job was being an electrician working for my Father in Law Contractor. He was great to work for but the job is so tedious and boring. He landed a large contract wiring a couple hundred apartments in Bryan Tx just outside the city limits. Just imagine walking thru all those walls pulling wire to each receptacle over and over and over and over. I hated it really bad. It is hard work laying the underground transformer wiring and piping. Not only was it hard work it was a long drive to Bryan everyday, even spending a few nights a week sleeping in one of the finished apartments on the floor, at least we had lights working. My Father in Law wired the Swiss Chalet in Houston in 1969 and the owner faulted on the payment, so he worked out a deal with the guy and allowed him to open without any lawsuits etc., he was able to just sign his tab for years until the final payment for his work was complete. It was a suit and tie place but my Father in Law and myself and the wife would go in and eat dressed like the rag muffins we were. They had great food ..
I once delivered leaflets, I would have a sack full and would post them in peoples letter boxes, sometimes the leaflets had vouchers so I'd keep a few back for myself, it was a boring job but I needed to earn while looking for full time work.
The two worst jobs were (1) de-tasseling corn in grade school (which was hot, dirty, humid hard work with no rest other than 1/2 hr lunch break) and director of software development for a TX company (which lasted about 4 days when I found out they didn't have the products they were selling). Another notable job was engineering manager for Digital Equipment Company, which was arguably the dumbest large organization I've ever worked for.
@Worst job I ever had, I'll have to put them in order, since none of them were great jobs. Most of us 'jack of all trades 'are not thrilled with our employment's. Day Labor Job, had me digging ditches while hubby aka Jake was standing around directing traffic! Lasted one day. Foreman must have been a woman hater. Giant ship repairs were no fun either. GM Assembly line was hard work, after 6 months I looked like a female weightlifting champion, hid my muscles under long sleeves. Working on huge barges stacking huge rocks into giant container for bridge pilings. My hands were bleeding and an older black man felt sorry for me and gave me his gloves.
I had several boring ones in my large history of jobs, but I would quit and had a new job a couple days later. Back in the day, jobs were plentiful.....
Back in my early 20s when I was a secretary I got a job with a company through an employment agency. The agency had an agreement with the hiring company that after 30 days of employment the company had to pay a commission. So I worked at the front desk for a few days answering phones, etc. and then they put me in the back setting up printing trays with all these dirty inky letters to be used for mail to their customers. It was a mess and it took me quite some time to get it all straightened out. My hands got clean by the end of the day though, because I was also told to clean the employee kitchen every day before I left. Long story short, on day 29 of working there, I was called into the office and they said I "wasn't working out" and "wasn't taking enough interest in my job". Fired! It seems I got all the dirty work done that no one else wanted to do just in time not to have to pay a commission to the employment agency.
The worst job was having no job. I had a wife and 2 kids, got laid off from a decent job, it was 1971 and the economy sucked. After about a month, I ended up taking a job in a God forsaken small town in NW Ohio out of sheer desperation. That job was not great but I stuck it out for >2 years until something better came along.
