At this moment, missing worklog reminder sends emails based on general work hours configuration (e.g. 8 hours a day is expected). However, it would be good to be able to define a separate parameter value for the missing worklog reminder, to be able to define work hours threshold below which a reminder email would be sent.
For example, we do not consider it to be a problem if an employee covers 7 working hours with his worklog entry. However, using current settings, if we switch on the reminder, he would get an email almost each day. That is why we do not use reminders at this moment.
