In 1300 the word labor meant a task or project.  It came to also signify trouble, hardship, pain and fatigue. The word entitle soon surfaced to describe the act of naming a chapter or a book. A century later it defined giving someone claim to a possession or privilege.

You don’t work free because your employer deserves your labor. You earn your paycheck; it’s not an entitlement.

On a far more cosmic scale Paul of Tarsus wrote this to the citizens and slaves in 1st century Rome:
“The wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord.”

Have you accepted that gift, God’s labor of love, which we cannot earn and do not deserve?

“For it is by grace you have been saved, through faith—and this is not from yourselves, it is the gift of God— not by works so that no one can boast.  Ephesians 2:8,9
