I'm a freight train driver. The roster is a full 24/7/365 operation, the pay rate is a flat rate all hours of the day with no extra at night or on weekends (only on public holidays). The majority of the work seems to happen at night. I've done railway shiftwork for 30 years and have had no social life since long before that so being an introverted hermit with no romantic life or socialising is quite normal for me. ;-) I've never really had a mon to fri daytime only job.
When I worked for companies it was almost always 8 hour night work , when I work the job I like I’m the boss and only work about 4 hours a day and make more money but the time varies because it works around the tides. I’m retired now but still do my job when I want to. Big difference between have to work to pay bills and working because you want to.
