Amazon alerted staff to fresh global job cuts through an email sent in error.
Workers at Amazon Web Services received a cancelled meeting invite containing a draft layoff message.
The email wrongly claimed affected employees in the US, Canada, and Costa Rica were already informed.
Senior vice-president Colleen Aubrey signed the message, calling the cuts “Project Dawn”.
Amazon cut 14,000 corporate roles in October and continues trimming pandemic-era hiring.
Chief executive Andy Jassy has warned AI could replace some white-collar roles.
The news followed fresh job cuts announced by United Parcel Service.
