Perhaps you should try some spelling variations:
"repartition du travail" » "repartition des travail", "preparation du travail"
"repartition et travail" » "repartition des travail", "preparation et travail", "repartition after travail", "repartition de travail", "repartition au travail", "repartition et travaux"
"preparation a travail" » "preparation _ travail", "preparation au travail", "preparation de travail", "preparation _ travails"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("preparation a travail") or ((("repartition du travail") or ("repartition et travail"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("preparation a travail") OR ((("repartition du travail") OR ("repartition et travail")))).
• Removing quotes may allow a broader search: (( preparation a travail ) or ((( repartition du travail ) or ( repartition et travail )))).
• Adding a wildcard symbol may retrieve word variants: (("preparation a travail") or ((("repartition du travail") or ("repartition et travail"))))*.
