>Then, as a biologist, it can be incredibly difficult to restrict your working hours, as experimental (e.g. cell culture) work can operate with delays or intervals. Stepping out at the wrong time means your cells die.
That's where personnel management comes in. I've got an undergrad intern at the moment, who has only a modest amount of lab research experience. In a month and a half, I've taught him molecular biology from scratch (beginning with the fundamentals of PCR) and from what i taught him, I gave him a list of 48 mutations. He designed primers to make those mutations, does the molecular biology, checks the sequences, then does the biochemical experiment on the enzyme that's being mutated. He's finished about half of the mutants. We are able to get this done because the experiments were planned out to be paralellizable and scaleable, and if something is finishing up when it needs to be picked up at the end of the day (like a transformation recovery), I do it, because he comes in early and I stay in late. I also drop in on the weekends to start cultures- but usually only briefly -, to make the most efficient use of his and my time. He is in usually around 9:00-9:15 and I make sure he leaves at 5:00 and I really get angry if he's around past 5:15 except in exigent conditions.
Bottom line: Even in Biology, you can restrict your working hours if you're a team player if you have good management skills.
If you're overworking. Since science entails failure that you cannot engineer your way out of - you will wind up burning out, since the working hard followed by failure is exactly an optimal way of conditioning laziness.
You're absolutely right, it is possible and even important to structure your experiments in such a way that they don't dominate your life. It's something that I've learned to do pretty effectively (and my chosen discipline makes it easier).
I think there are certainly organizational things that can be done to facilitate more reasonable working hours, and I've seen this done well in industrial settings. From pipelined experiments to working with automation, technicians, and teammates.
With all that said, it's not easy, especially as a junior faculty member with limited resources. Building a sane lab environment is 100% worth it IMO, but it is challenging and comes with a few perceived compromises.
Biology could also be a very competitive field that seems to have devolved into basically a rat race. How do you compete with your equally capable peer when they work 80 hours a week and you work 40? Yes, its not sustainable, but maybe that's where we are right now (disclaimer, I don't work in Biology, but have friends that do).
