Successful launch of the Netherlands Inclusiveness Monitor

Everybody can participate and is valued for who they are, irrespective of gender, age, ethnicity, sexual orientation, or religion. That’s the key of being inclusive. The Netherlands Inclusiveness Monitor (NIM) investigates the initiatives organizations take to become more inclusive. It connects these findings to the experiences of employees and provides organizations with evidence-based advice on which steps to take to become truly inclusive.
