Do Mexican workers work long hours?

CNN today:
« The South Korean government was this week forced to rethink a plan that would have raised its cap on working hours to 69 per week, up from the current limit of 52, after sparking a backlash among Millennials and Generation Z workers.
Workers in the east Asian powerhouse economy already face some of the longest hours in the world – ranking fourth behind only Mexico, Costa Rica and Chile in 2021, according to the OECD – and death by overwork (“gwarosa”) is thought to kill scores of people every year. »

It's arrived at through an aggregate formula. More of an estimate than true working hours based on actual employment numbers.

Any workers I have had started at 8:00am and finished at 6:00pm. They took a 30 minute breakfast break and then a 1 - 2 hour siesta around 1:00pm. They also worked a half day on Saturdays.

Construction crews where I live usually start at 8 and knock off by 4 or 5. Half hour breakfast break, one hour lunch/siesta break. Never seen them work until 8 unless they are doing a big concrete pour and have to get it all done in the same day.
