I have created a workflow to send mail (user decision to approve or reject buttons) to an approver. If he doesnt respond to it till 3 days, a mail should be sent to his higer level person (say supervisor) and this supervisor should approver or reject the notification. If supervisor also doesnt take any action till 5 days a mail should be sent to the higer level person(manager) and manager should approve or reject the notification. This escalation goes on till 5 levels.
any suggestions and solutions would be very helpful.
