U.S. tech worker here. The only time I’ve ever worked 60-80 hour weeks was at a much smaller company, where for a month or two leading up to a trade show a whole bunch of work that had been put off was attempted to get crammed into the product. At my subsequent BigTech jobs I’ve never been asked/required to work more than 40 hours a week. I mean, nobody was tracking exact hours, but nobody was also pinging me at 8PM or on the weekend and expecting me to be working.
