company ke bare me karmachariyon ke vichar janne ke liye kiya janewala sarvekshan or company ke bare me karmachariyon ke vichar janne ke liye kiya gaya sarvekshan (as the case may be)

As you wanted something different than the usual vocabulary (and which Arun Singh has already suggested), this could be an option to consider, although I doubt whether you would want to use such a long title.

मेरे मित्रों ने पहले ही आपको ऊपर उत्तम सुझाव दे दिए हैं, फिर भी मैं आपके समक्ष दो अन्य विकल्प प्रस्तुत कर रहा हूँ:

KarmchAriyo(n) kii rAye say sambandhit sarvekshaN = कर्मचारियों की राय से संबंधित सर्वेक्षण

OR

KarmchArii rAye sambandhii sarvekshaN = कर्मचारी राय संबंधी सर्वेक्षण
