Question
Imagine you had a simple user interface next to the coffee in your work kitchen. Every employee in the company will use this interface at least once a day.
As HR that cares about talent retention and employee engagement, what would you ask?
Answer
"How can we help you?"
This is broad enough to cover work-related enquiries ("We need more training in X") and personal ("I'm feeling very stressed lately"). Both are important for HR to know and develop solutions for.
To achieve meaningful results however, this question has to be asked of the employees by the managers and leaders of the organization as well, on an ongoing basis. No technology can or should ever replace that.
