Linked as one- many(multiple workers times to each job)
This may not be what you actually have. Many workers to one job for sure, but can a worker not work on more than one job? If so, you have a many to many relationship between workers and jobs. That may not be your issue, though. If your report "groups by" job and the job value is calculated in the job footer, you may be OK. I'd advise you to consider if your current design supports many to many or just one to many as I'm saying. You might not have your tables designed correctly.
The more we hear silence, the more we begin to think about our value in this universe.
