The Paris prosecutor's office has requested a euro30,000 ($42,000) fine against an association closely linked to the conservative Roman Catholic group Opus Dei.
The association, ACUT, and two of its followers are facing charges of "clandestine work" and "remuneration contrary to dignity" stemming from allegations by former disciple Catherine Tissier that she was forced to work with little or no pay for more than a decade.
Tissier was 14 when she joined a hotel school in eastern France also linked to Opus Dei. She followed the group's spiritual path and began working for the school but alleges she never saw her salary.
Prosecutors on Friday also asked for euro6,000 ($8,000) in fines against the two Opus Dei members.
