Is there some way to inform the users of delinquent time for the previous week of work?
The User/Project Time Report was created for this purpose. Once the report is run with the parameters that you specify, you have the choice to send emails to specific users letting them know about the deficiency of their time for the date range you chose. You also receive an admin email with the details as well as the employees names that received the email. The users have a version of this report available to them also. It does not have an email section but it will show them their time and deficiencies as per their parameters.
