can't call (one's) soul (one's) own
Spends most of one's time working for others. Now that I've started working overtime four days a week, I really can't call my soul my own.
can't call one's soul one's own
To be very much in debt or bondage to another; to have lost one’s independence. This turn of phrase dates from the sixteenth century and has been repeated ever since. In Dickens’s The Old Curiosity Shop (1841, Chapter 4), “She daren’t call her soul her own” is said of Mrs. Quilp, wife of the tyrannical dwarf, Daniel.
