You can use the 'company-name ' field selector and set the 'current-company' field selector to True to retrieve employees on your network:
GET http://api.linkedin.com/v1/people-search?company-name=Apple¤t-company=true
This will bring all the Apple employees who currently work there.
But the People Search API is part of the LinkedIn Vetted API Access Program. You must apply here and get LinkedIn approval before using this API.
