You are using Form view with what appear to be different portals for different days of the week? Hope these arent' repeatin fields or we have a real mess here to straighten out.
You should have a relationship that looks like:
Jobs::__pkJobID = HoursWorked::_fkJobID
For an explanation of the notation that I am using, see the first post of: Common Forum Relationship and Field Notations Explained
HoursWorked would have one record in place each row shown in your portals or repeating felds.
Then you can produce a Summary Report baed on HoursWorked where you can perform a find or use Go To Related Record to pull up all the HoursWorked records for a given Job. Sort these records on a list view with summary fields and sub summary parts and you can get the same report shown here, but grouped by type of work.

Unfortunately they are repeating fields, but I am in the works of replacing those as I recently read through the forums that they are evil still remnant of the original FM versions.
I thought a summary report would be the way to go but I know very little about them and how to manipulate them so when it didnt look right, I kind of went another rout. But that is probably caused by repeating fields
Repeating fields are almost never the best choice for your database design. They have been superceded by related tables over the last decade and now only have a few very limited uses where they still are advantageous to use.
