If the company is at a point it recognizes that this is needed then it is probably really bad and at a point where people probably need 3-4 weeks. It takes companies forever to admit to an issue and they never seem to enact a solution that gets things to where they need to be. They love half measures. It lets them feel good about "doing the right thing" without actually expending the needed resources to do the right thing.
I don't work in that industry. I don't particularly work much past 40 hours a week. Stress and burnout are still at the point it takes the whole weekend on a normal week to finally unwind. A bad or stressful week can take 4 days. That is time needed without dealing with other crazy (home repair, etc) but actual down time. Assuming you lose half a day to other stuff that spins me up I'm at a half day in the hole each week to be refreshed for the following week (on a normal week). That builds up over time and has impacts.
