Speaking as a fellow Brazilian: so account for it beforehand, in the same way you should account for 13th salaries and other "hidden" worker rights, which are liabilities in the accounting sense.
Yeah, that's how we have always hired, and I don't see a big problem with CLT (the Brazilian employment law), perhaps with the exception of how vacation time and union membership is handled.
It's bizarre that the threads on this post seem to straddle "founders are only in it to make money off the back of their employees" and "worker's rights and compensation are onerous" simultaneously.
