That really depends on what you mean by "tech worker" but moving from knowledge work to trade work rarely works out unless you're already a master craftsman and just switching to an artisan business full time. The salaries are significantly lower, to the point where 90th percentile electricians often make less than 10th percentile engineers [1]. It is a physically demanding job that will lead to health issues and is no more immune to psychologically abusive management than tech with added life-or-death liability.
Don't confuse owning a business that hires its electricians to customers with actually being an electrician. The former is very lucrative, the latter much less so. It takes many brutal years to get from the latter to the former.
[1] As opposed to QA, customer service, etc, which are more comparable hence the "tech worker" caveat
