Alert schedules allow you to define a series of time-based alerts which can be attributed to an individual employee. These alerts are triggered to run after a defined number of months have passed from the defined start date of the schedule. Typically, this is the date the employee joined the organisation. Alert schedules are a convenient way to setup alerts for employment anniversaries, performance reviews, pay reviews and other monthly/quarterly/annual events when an employee joins the business.
You can also specify a different start date for an alert schedule when assigning it to an employee, to cover different processes you may wish to follow in the system.
