Companies that promote the "996" culture (working from 9 am to 9 pm, 6 days a week) are a major red flag for any employee. This model might only be justifiable for a founder with a huge equity stake, never for an average employee without extraordinary compensation. Furthermore, these extended hours don't usually translate into greater real productivity.
This debate is part of a critical redefinition of work. Technology has increased productivity, but wages have stagnated, breaking the social contract. As in the past with labor laws, urgent change is needed to avoid a crisis, prioritizing a quality life and a legacy to be proud of, not senseless exploitation.
