How to prevent users from deleted linked tables


So I have a big growing database and about 8 members that will be using it everyday to add data. Since I’m managing the work that is being done, how would I prevent users from accidentally clicking the X on a linked record from a linked table? I know that the history pane keeps a running record but what if I don’t find out that something has been de-linked. I know in ACCESS users wouldn’t even have this functionality. They would only be able to add records from other tables.
