Two words -- Life and Livelihood -- seem to have the same root. Whether or not they share the same etymology, in reality they are connected:

"Work is fundamental to the dignity of a person. Work, to use an image, 'anoints' us with dignity, fills us with dignity, makes us similar to God, who has worked and still works, who always acts..." Pope Francis
"I address a strong appeal from my heart that the dignity and safety of the worker always be protected." Pope Francis
