Well since Brexit the people want a say in so called "free" trade agreements which create growing middle classes in developing countries and gut it in the developed ! Fair trade was the answer but the corporate/politic class has sold out the middle class long ago and they want a say in how these agreements are beneficial to the citizens of the developed world.

Export products not jobs as an example -> Keystone pipeline likely to be approved but build a refinery here and export the finished products to the US and the rest of the world not the raw material (oil sands bitumen to be processed in refineries in Louisiana)
In any negotiation or renegotiation, the guiding principle should be this: Enter into a free trade agreement only if it both increases total trade and reduces our trade deficit without job losses
Can the Corporate/politic class listen to the people for a change ? If not, their votes will as seen in recent 2016 elections.
