I am definitely in favor of ending the 6x1 work schedule in Brazil and worldwide. But...

 ...I fear the serious side effects this measure could cause in the medium and long term, such as mass layoffs, not only because Brazil is once again experiencing a sensitive economic and social moment under a left-wing government, but also because the business class, especially the wealthiest, tends to exhibit psychopathic personality traits and would have no qualms about using the end of the 6x1 work schedule as an excuse to lay off workers, in addition to committing other injustices against the working class, aiming, of course, (always) at increasing their profits...

Therefore, I also fear the effects caused by the supposedly well-intentioned measures of left-wing governments, not just this one, the end of the 6x1 work schedule, because they seem reckless, both governments and so-called progressive masses, regarding the essentially hierarchical nature of the relationships between factors within a socioeconomic scenario or context, organizing themselves like houses of cards where the removal of some cards can mean the fall of the castle or, at least, a worsening of its base. to support it. Again, as if they were completely ignorant of these relationships and how altering them without in-depth study, which would most likely result in the conclusion that other equally popular, necessary, and complementary measures should be promoted, could bring unintended consequences. For example, the constant disregard by the progressive wing for some of the structural problems, primarily in Brazil, that most hinder the lives of both employers and employees, such as the high tax burden and its use to sponsor very high salaries for certain classes of public employees, such as politicians, only ratifies and reinforces the veracity of my concern. If they joined the chorus of those who want a reduction in taxes, especially some that seem to mock their authors, but, on the contrary, because they are among those who most advocate for the continuous increase in the tax burden, to continue sponsoring "welfare measures" that, in turn, keep a potentially growing part of the population dependent on the state, precisely serving as electoral cattle...

Regarding the end of the 6x1 work schedule and the criticism from the right

 It seems that the problem, if there is one, with ending the 6x1 work schedule (analogous to slavery), is that it would further increase employers' costs, especially those with "smaller economic stature," stifling the economy. However, as the right itself also criticizes, the real problem is not the worker or employee having the right to rest that is not limited to one day a week, as they seem to claim, but the high tax burden in Brazil, which "eats up" a large portion of the population's earnings. Therefore, instead of many on the right, stupidly and/or perversely, opposing the end of a cruel system of economic exploitation, perhaps simply because it is a left-wing agenda, they should focus on reducing taxes and, at the same time, supporting this measure, since both benefit workers and entrepreneurs, in short, the economy itself...
