Referring to the Employee Central Handbook and on page 47 we see a section on 'View Workflow Approval History'.
However such an item does not come in our system once we have upgraded to people profile.
"Veiw workflow history" button is available for the records in history for which a workflow exists. This button is visible just beside Edit button.
