Abstract: Systems and methods are provided for receiving schedule information and providing notifications to participants of the schedule and scheduled jobs or tasks. Employees may define preferences for the content, mode, and timing of notifications. Notifications may be sent via text message, including SMS and IM text messages, and also via email, telephone call, pager, and fax. Employees may be enabled to respond to text message notifications either confirming or rejecting scheduled jobs or tasks. Attendance of employees at scheduled jobs or tasks may also be tracked by receiving text messages or GPS information from the employees' cell phones. System and methods are also provided for sequentially notifying other employees, in order of employee priority, of opportunities to cover for employees who are unable to fill assigned jobs or tasks.
