hey guys i need to consult you working people about how much hours we should work in a day

So im rn looking for a opinion about work hours. My first job was working at the construction i worked 10 hours a day and i had 1 hour break divided by 2 so two half hour breaks in this 10 hours. That said i was 11 hours on the work site. I didnt mind it that much but the deal breaker was a commute to work(i have worked abroad) which was 7 hours one way. So in a week i had 50 hours of work time + 14 hours commute both side(at least my paycheck was good)(in one day i have earned 120 buscks).

And rn i have found my self a local second job that wants me to be a 14 hours every day monday to friday or 6 hours in friday and starurday sunday both 14 hours(just working weekends). Paycheck is in my opinon ass because it requires really much physical and psychical strenght to endure it. yesterday i had my first day and first 14 hour and after that day my back is lil hurting and i think that this shi aint worth it(100 dolars paycheck for 14 hours) And i had maby 1 hour break.

And here becomes my question am i sissi who is crying about nothing and i have to get a grip

Or im right and both of this work hours are just f*****up and not worth it
