Dear Villis,
Thank you for the query.
I take this opportunity to suggest to members to kindly search the web before posting our query to get quicker answers.
For example, had you searched the web using Google, you would have found the Policy Document of Nestle at http://www.nestle.com/Resource.axd?Id=E9EC6B84-3562-4FD3-99D6-51AD66F37CE8. You can also find it by searching for "HR Policies + basis for effectiveness" on Google.
Here is an extract from that document:
"They are in essence flexible and dynamic and may require adjustment to a variety of circumstances. Therefore, its implementation will be inspired by sound judgment, compliance with local market laws, and common sense, taking into account the specific context." (I have altered the font to Bold.)
I hope that answers your question.
Best wishes,
Simhan
