Click the Mailings tab of the ribbon, and click the Labels button near the left
end.

In the dialog, click the Options button. In the Options dialog, set the Label
Vendors dropdown to Avery US Letter or Avery A4/A5, depending on what kind of
stock you have. Then choose the appropriate product number from the list. Click
OK.

Unless you want all the tabs to say the same thing, leave the Address box empty
and click the New Document button. You'll get a document containing a table (if
you don't see it, click Table Tools > Layout > View Gridlines) whose cells match
the tabs on the stock. Type a different tab text in each cell.
