Let's face it. Most startups are straight up toxic. Been there, done that. Never again.
On the flip side, though, if I saw a startup that enforced a proper work/life balance for their employees, while fairly compensating them with pay, healthcare, and clearly defined Vacation/PTO policies (none of that "unlimited vacation" bullshit trap that startups like to pull), and perks like 7 weeks of PTO for new fathers/mothers, then I would actually consider working for a startup like that.
