Amazon is rolling out automated packaging machines while offering some employees up to $10,000 to quit and deliver packages as contractors instead.

The online retail giant is currently debating whether to expand the use of such machines, which can scan and package items with custom-made boxes depending on their size. Amazon box packaging is a job currently held by the company’s human employees.

The machines could replace 24 workers at every warehouse they are placed. This means that the jobs ofover 1,300 people could be cut across the country, as the company is considering “installing two machines at dozens more warehouses,”Reutersfirst reported.

The machines, which were built by Italian firm CMC Sr, can package anywhere from 600 to 700 boxes per hour. The machinespackage items at “four to five times the rate of a human packer,” according to Reuters.

In a statement to Reuters, Amazon said it was testing out the equipment with the end goal of benefitting the consumer.

We are piloting this new technology with the goal of increasing safety, speeding up delivery times and adding efficiency across our network, Amazon said. We expect the efficiency savings will be re-invested in new services for customers, where new jobs will continue to be created.

News of the packaging machines comes just as Amazon is expanding a company program that encourages workers to quit in order to deliver packages as contractors instead.
