Hi Luciano,
I understand.
Are your employees using the celpax before they leave work?
you have to ensure that you have your ergonomics right, the installation has to be done properly becuase:
It is important that the button is pressed at the end of the working day.
We can look into your data to give you an indication of which % of your mood KPI might be influenced by these pulses, but you can expect it to be less than 5%.
Sometimes employees try to "protest" via the Celpax device, in that case we recommend you look into the underlying problem.
Note that process do happen, but have limited impact on the data.
