Click and hold on an unscheduled job, then drag it to the time/technicians that you want to schedule the job for on the calendar.

To move a scheduled job to unscheduled, click and hold on the job and drag it to the unscheduled column. This is useful if a job needs to be moved, but you don't have a new time for the job yet.

Note: When a job is unscheduled the technicians are not removed from the job.
