For new members the 30 days (60 days where a paper application is required) starts on the date that the member is added to Compass.
The 30 (or 60) days does not start from the “start date” of the role, because it is possible to enter role start dates either in the past or in the future, and to use this date would mean that some people would miss the reminder e-mails.
People added to Compass will receive an e-mail (copied to their line-manager and Appointment Secretary) to remind them that they have 30 (0r 60) days in which to submit a disclosure request.
