Ask HN: Is it a bad time to take a sabbatical?

A tech employee (PM) at a startup with 2 years as a PM and about 10 years as a dev. Have been continuously working for those 12 years without a good break and I fear I might be on the verge of burnout. I’m looking for advice on the best approach to taking a sabbatical. The economy is what scares me. I don’t want a 4 month sabbatical to turn into a 12 month break. Is it a good time and how would you approach it? We have a dual income home and we will break even on a monthly basis if one of us takes a sabbatical. Any advice would be greatly appreciated. Thanks!
