Forms :: Create Form To Update Multiple Tables At Once

I'm working to create a staffing database that houses changes to staffing week over week.

I have one primary table, the "empMaster" table, that stores the employee's name, contact information, etc. I have other individual tables for noting which employee reports to which manager, what their business title is, what group they're in, their training history, etc.

Once I've populated the empMaster table with employee information, I want a form that allows me to update each of the other tables IF there as a change. Some weeks will have a manager change, some only a business title change, some a group change, some a training change, some all of the above. The problem I run into is that I will sometimes process hundreds of changes a week, sometimes only 10-20 so I almost have to use datasheet view for mass edits. I'm relatively new to Access and I'm having a hard time getting my form to allow this level of flexibility and to update all fields needed.

When I build a form that includes more than two tables (let's say I want to update a Manager and a Business Title), the form will not work and populates nothing. I believe it's because Access wants there to be an existing record to match to across all three tables and there will not always be.
