Perhaps you should try some spelling variations:
"quality of workers life" » "quality of worker's life", "quality of workers like", "quality of workers lived"
"quality of worker life" » "quality of work life", "quality of working life"
"quality of works like" » "quality of work like", "quality of looks like", "quality of worm like"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (("quality of works like") OR ((("quality of workers life") OR ("quality of worker life")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"quality of works like\") or (((\"quality of workers life\") OR (\"quality of worker life\"))))".
• Removing quotes may allow a broader search: (( quality of works like ) or ((( quality of workers life ) OR ( quality of worker life )))).
• Adding a wildcard symbol may retrieve word variants: (("quality of works like") or ((("quality of workers life") OR ("quality of worker life"))))*.
