Sorry to confuse you. I thought you were doing a month at a time hence the month reference. As for the rest I obviously didn't get your table set up. Basically you have to have a source that is a 'master list' of all your employees. From there you have to outer join that into the report and use it for grouping.
The trickier part is that if you start to use crystal for the select statement you can turn an outer join back into an inner join hence my recommendation of using a Command (if possible use a stored proc or view in your source rather than a command).
What are all the tables you are using and how are they joined? Do you have source table of active employees you can use?
