I am of the firm opinion that editors must complete all major edits prior to starting the layout in InDesign. If they insist that they can't possibly edit the content until the file in already in InDesign, then it would be worth taking a look at the InDesign/InCopy workflow, which allows them to edit the copy after it has been placed and formatted in InDesign, without disrupting your layout. InCopy is included with your CC subscription. The others can use it for about $5 per month.
