The creation account goes deeper than just “work”. God commanded man to subdue the Earth and procreate. Despite man’s fall in the Garden, God never revoked those first two commands. Sin introduced “sweat” into the subduing of the Earth and “pain” into child birth but we are still supposed to carry out those commands.
When we die and go to Heaven, it is my understanding that we don’t have to work, food stamps and generous pension checks for everyone.
