Workday, the platform many big companies use for things like paychecks and time-off requests, went down unexpectedly.
This glitch left employees at places like Walmart, Target, and Chipotle unable to check their pay or request time off.
Workday has put some systems into maintenance mode and is posting updates every half hour.
Workday backup test caused data lockouts
The trouble started during a test of Workday's backup systems, which led to data issues and locked-out users.
With more than 11,500 organizations relying on Workday for payroll and HR tasks, the outage is a reminder of how much businesses depend on these platforms.
Workday has apologized but hasn't given a time for a fix yet, highlighting why strong backup plans really matter in today's digital workplaces.
