In most countries it's a lot more. Throughout human history it has typically been a lot more.

Getting the work day down to 8 hours required violent riots that resulted in bombs being thrown at the police and people being hanged after quick show trials. And even once the work day was reduced to 8 hours, it was a while before the work week was reduced to only 5 days. Interestingly, the US initially led the world in reducing the length of the work week. But, these days it has been completely captured by oligarchs and unions are the weakest of any country in the developed world, so it has fallen far behind on any kind of worker rights compared to the rest of the world.

40 hours may feel like a lot, but throughout most of human history only working 40 hours was a privilege available only to the nobility. It's possible to get the 40 hours reduced even further in the US, but it will probably once again require massive demonstrations, and it seems unlikely that it will happen without violence and death.
