Not sure what you mean there.
Sinecure n. (from Latin sine = "without" and cura = "care") means an office that requires or involves little or no responsibility, labour, or active service.The term originated in the medieval church, where it signified a post without any responsibility for the "cure of souls", the regular liturgical and pastoral functions of a cleric, but came to be applied to any post, secular or ecclesiastical, that involved little or no actual work.
Sinecures have historically provided a potent tool for governments or monarchs to distribute patronage, while recipients are able to store up titles and easy salaries.
Cushy job, whatever. Maybe sinecure was not quite the word. Sooner or later one runs out of cushion.
