Bank tellers, cashiers, postal workers, and the jobs of administrative assistants are among those forecast to decline by 2030, according to the World Economic Forum's Future of Jobs Report, which was released ahead of the group's annual meeting in Davos, Switzerland, later this month.

In all, the World Economic Forum (WEF) estimates "new job creation and job displacement" will amount to 22% of today's total jobs, and specifically, 170 million jobs will be created, equivalent to 14% of current employment. This growth is expected to be offset by the loss of 92 million jobs, resulting in a net growth of 78 million jobs by 2030.
