In a wide-ranging television interview as conference got under way, Mr Corbyn was asked if he would feel obliged to respect a vote by delegates to support another plebiscite.
Under the party's plans if it won power, both public and private companies with more than 250 staff would be legally bound to have worker directors elected by the entire workforce.
But, he said, if Labour's conference "make a decision, I will not walk away from it and I will act accordingly".
There was a similar message from deputy Labour leader Tom Watson, who told The Observer: "Jeremy and I were elected in 2015 to give the Labour Party back to its members".
"We don't know what it would be", he told the BBC. Not doing so will result in a "no deal" Brexit, in which the United Kingdom leaves the bloc without an agreement and reverts to World Trade Organisation rules on trade with the EU.
He told Sophy Ridge on Sunday: "It seems to me inconceivable that if the Labour Party conference decides that it wants a manifesto pledge on a people's vote that we would defy that decision".
The shadow Brexit minister said Labour would consider a second referendum in the event of no deal.
The poll is aimed at allaying the anxieties of Labour voters in pro-leave constituencies, who fear that opening up the possibility of revisiting the Brexit vote could alienate their supporters.
"But I would look at what the question is on offer and I would want to know what the deal is that comes out of the negotiations, if that happens", he added.

But in contrast to warm words from Labour's leader and deputy leader, shadow business secretary Rebecca Long-Bailey warned people would be "concerned" by a second European Union referendum.
But Ms Chapman said her party would not accept no deal and instead consider three alternatives.
