As long as you consider surviving and having your children supported financially to be worthless, yes, the labor was free.
But free definitely implies they did in exchange for nothing, which is false.
But you may gladly go along with all of it, even the risk of death, because of what you care about. Your family, your town, your country.
Which is why claiming the work of either men or women is done for free is silly. There are so many other values in life.
