1. It's the right thing to do, ethically
We can look at this from two viewpoints.
The negative: if there's a group of people in your organisation who are being unduly harmed by conditions, it's the ethically correct thing to do to change those conditions. Highly Sensitive people can often be in this situation at work - unbenknownst to others, especially supervisors. Many conditions - in the physical/sensory environment and in processes and culture - which are considered normal in workplaces are actually harmful to people with this temperament. These halt their progression, cause undue stress, and prevent them from using their gifts for the greater good. If you become aware of the fact that this exists, which it does, then ethically, you need to do something about it.
The positive: if there's a group of people in your organisation who have unique gifts, but whose potential isn't being fully utilised, both they and the organisation are suffering for that lack. That's a resource that's not being tapped, and a valuable one. Tap into it; nurture it; help it develop. Ethically, if there's a resource like this, and it's going to waste, then caring about employee wellbeing and organisational success means learning about it, making use of it, and improving it. Or else that resource should be going where that will happen.
2. Benefits for everyone
A thriving Highly Sensitive person at work brings benefits to the rest of the organisation. Better ideas, wiser decision, greater awareness of dangers, problems and opportunities, improved communication, and more.
3. The things which help HS people thrive are often the things which need to be changed anyway
Tamara - Sensitive Thrive is my consulting business. I believe that the world needs Highly Sensitive people who are flourishing. We need their hope, insight, wisdom, and awareness of beauty and possibility. My vision is to help create a culture where this temperament is known, understood and valued; where organisations seek Highly Sensitive people to work for them, because they know what they can do. Where HS people feel like they fit in their workplaces, because those workplaces also fit them. A world where HS people belong, thrive, and flourish, and the world is better for it.
