Technology issues strain work from home efforts at big US banks

Citigroup, the third largest U.S. bank by assets, has about 200,000 employees worldwide, according to filings.

NEW YORK: Citigroup Inc asked its non-essential workers across North America to hold off on logging into its remote access system until 1 p.m. on Thursday, as it braced for many employees to begin working from home, according to sources familiar with the matter.

The move is meant to minimize the time that Europe-based employees and U.S.-based employees are logged in at the same time to prevent the system from being overwhelmed, one of the sources said.
