Is this real?

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.

Construction workers are usually on the job at 8 am and finish at 8 pm. However, they nearly always take a two hour lunch/siesta between 2 and 4.
Not sure about others like retail or restaurants since the doors being open to the public are not indicative of the work being done behind closed doors.

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.
