False. The confusion of slavery with servitude is endemic with some.
The reality:
In fact
Instructio Number 1293 signed by Bl Pius XI is in* Collectanea*, Vol. 1, pp. 715-720 and is an “Instructio” of the Sacred Congregation of the Holy Office on some disputed questions, including questions of “servitude,” issued in 1866.
The
Instructio itself, right at the point at which it declares even “servitude itself considered in itself and all alone (per se et absolute), is by no means repugnant to the natural and divine law,” acknowledges that “the Roman Pontiffs have left nothing untried by which servitude be everywhere abolished among the nations.”
This SERVITUDE is of three kinds:
(a) penal servitude;
(b) indentured servitude; and
(c) the servitude of prisoners captured in just wars.

Let My People Go
The Catholic Church and Slavery
By Mark Brumley
…“slavery” is the condition of involuntary servitude in which a human being is regarded as no more than the property of another, as being without basic human rights; in other words, as a thing rather than a person.
Under this definition, slavery is intrinsically evil, since no person may legitimately be reduced to the status of a mere thing or object and thus become capable of being the property of another person. This form of slavery can be called “chattel slavery”…
…However, there are circumstances in which a person can justly be compelled to servitude against his will. Prisoners of war or criminals, for example, can justly lose their circumstantial freedom and be forced into servitude, within certain limits. Moreover, people can also “sell” their labor for a period of time (indentured servitude)…
