The most likely outcome of this is that exports are sold at the price they are at now, not cheaper. The workers are paid the same as they are now, (which is the market rate). And the difference in what's normal and cost savings from TTIP will go to company bottom line. And the top officers at the company will collect a performance bonus.
The unlikely scenario is that the price comes down and more units are sold and/or the difference in export costs is divided between the workers to pay them above market rate.
