Project managers are usually anxious about the progress of their own projects. However, the above workflow sends emails to the project manager mailing list, so this means project managers will be receiving reports on projects they aren't involved with. (Their situation is different from top management, who is interested in over-time hours of all employees.) But if the date and name of the reporting employee is included in the subject line, this would make it easier for project managers to filter through the emails they don't need.
Of course, there will inevitably be some reports that don't need to be sent to project managers at all, such as work-time reports by project managers themselves, or reports that merely say, "I was at a seminar all day." If you want a workflow that can bypass emails for these kinds of reports, try the below workflow, which includes a "Do-not-send-email-to-project-manager" checkbox.
