There will always be two ways to build an identity.
The first one is founded on differences and contrasts.
We are different (from them).
Our team is the best performing in the company.
They do not care as much as we do.
When I see them, it makes me want to give my best to beat them.
The second one is founded on unity and commonalities.
We all work to have long lasting impact.
Our teams share the values of transparency and hard work.
We are in this together.
Our organisation wants to be a place in which people of different background can express their best work.
Which one you pick is an active choice, one that needs to be reaffirmed over time, one that you need to be aware of in the first place. So often we slip onto the first option simply because it is the easiest to put into practice. Be intentional.
