Editing to Avoid Sync Breaks
One way to avoid breaking sync is to maintain the duration of the track when you add or remove material, as follows:
  When adding material to a track, use the Overwrite function instead of Splice-in, whenever possible.
  When removing material from a track, use Lift instead of Extract. (The Lift function leaves filler of the same duration when you remove footage.)
  When performing Segment mode edits, use the Lift/Overwrite function instead of Extract/Splice-in whenever possible. (Lift/Overwrite leaves filler behind and overwrites material at the new destination, maintaining sync in both cases.)
  In Trim mode, you can sync lock tracks to avoid breaking sync, or you can use the Alt key (Windows) or the Ctrl key (Macintosh) for adding black during trims, as described in Maintaining Sync While Trimming. You can also perform dual-roller trims (that maintain duration) instead of single-roller trims.
There are many cases in which you cannot avoid splicing or extracting material, or performing single-roller trims that break sync.
