There's a chance that dockworkers at major ports could go on strike, which would mean ships wouldn't be able to unload goods.
This could lead to shortages of products, especially during the holidays, and make everything more expensive.
The dockworkers and port authorities are trying to negotiate a new contract, but they need to reach an agreement by October 1st.
Businesses are worried that a strike would have a big impact on the economy, especially since Christmas shopping is just around the corner.
