Let's just talk tables for a minute. I am looking at your Relationship Tool and this is what I see:
1. Using a non-primary key as a foreign key. Every table is linked to Contacts via its [ID Number] field, that is wrong. Since [ID] is the primary key of Contacts that is the value/field that should connect to every foreign table. However, if [ID Number] is unique to every Contact you can use that, in which case you get rid of [ID] entirely and assign [ID Number] as Contacts primary key.
2. [ID] in every table. You have 13 fields in your database called [ID], that's going to be confusng when writing queries. I suggest prefixing every ID with the ID it is the ID of (e.g. ID_Calls, ID_Sanctions, ID_Promotions, etc.).
3. Non-alphanumeric characters in names and beginining tables with numbers. Using non-alphanumeric and underscore characters in names makes coding and querying more difficult. The same goes for having a number as the first character of a table. You should rename your fields/tables to eliminate that ([1 Main Employees]--MainEmployees, [ZIP/Postal Code]-->Zip)
Then, for your form issue I would have 1 form with a tab object that has 12 tabs each holding a subform. The main form would be based on Contacts, then you build a subform for every other table and use a tab object and place each subform on a different tab.
