Loading and unloading operations resumed at Brazil's biggest port, port authorities and a labor group said, after stevedores ended a one-day stoppage the previous day in protest of rule changes limiting how many shifts they could work.

The strike slowed loading of container ships and solid but not liquid bulk goods. The stoppage was short lived with about half of the ships berthed resuming loading, the port said.

Port spokesman Sergio Saraiva Coelho said wet weather had become the main impediment to loading of bulk goods such as sugar and soy which are poured into ships' holds, but only in dry weather to prevent cargoes spoiling. (Reuters)
