A headless shift-coverage engine handles last-minute absence replacements for retail chain operators. It ingests call-out texts directly from employees, queries the existing scheduling database to identify eligible replacements, and executes parallel SMS polling until the open shift is claimed.

Store managers typically resolve dropped shifts by dialing through manual phone trees or blasting messages across scheduling apps like When I Work and HotSchedules. Both methods pull operators off the retail floor to monitor incoming replies and manually negotiate roster changes.

Replacing the manual call-down list with programmatic SMS polling ensures autonomous execution and immediate resolution. Open shifts are filled without human oversight, requiring manager intervention only if the automated system exhausts all available staff options.
