In the US, much of the abolitionist movement was based not just on the pure righteousness of the cause, but also the objection of many workers (farm and otherwise) of competition of slave labor (esp after Dred Scott). In this, they had something in common with the Populares of the late Roman Republic. I would hardly be the first, after all, to draw a comparison between the Roman Latifundia and Southern Plantations.
So, what if there was an abolitionist - or at least anti-slave - streak to Roman politics? There certainly was a manumission movement that peaked around the time of Augustus, but that was entirely about slave owners choosing to manumit their slaves.
One possibility could be that the Gracchi and/or the successors suggest, rather than trying to break up the vast estates in Italy, they set limits to the number of slaves that a single citizen can own. Or maybe they ban slave labor from the ager publicus (which could benefit rich Senators who could lease out land to citizens who would end up as clients). Maybe something extreme, like making the ownership of slaves a government monopoly, and renting out said slaves (think of prison labor in more recent times).
Or perhaps this actually grows to include an objection to slavery as an institution. That is the least likely, but if the masses are agitating against slavery for economic reasons, and enough of the elite are manumitting their slaves, perhaps such a message could emerge.
