Inc. is raising wages for its hourly employees after a majority of workers at one of the e-commerce behemoth’s warehouses voted not to unionize.

The company stated on Wednesday that over 500,000 of its employees would see pay increases of between 50 cents and $3 an hour. Amazon, which offers a starting wage of $15 an hour and employs roughly 950,000 people in the US., stated that the raises represented an investment of more than $1 billion. 

The pay boost covers a variety of workers and schedules, but averaged over the total number of employees Amazon stated that would be affected, it would amount to roughly $40 a week per worker. 

Amazon stated that its starting wage remains $15 an hour. The company refused to say what the average raise will be for workers and stated that it depends on factors such as how long an employee has been at the company.

A company spokeswoman stated that Amazon declined to proceed with its pay review from the drop to increase wages now. She refused to say if the raises were connected to the union election in Bessemer, Ala., but stated that they are connected to hiring and maintaining competitiveness for workers. Amazon said it is now hiring for tens of thousands of jobs throughout the country.
