You pass the t-shirt test when people proudly wear a t-shirt with the logo of your organization on it.
Would you proudly wear a t-shirt with your own name?
I would.
Would you proudly wear a t-shirt with the name of your spouse?
I would.
Would you proudly wear a t-shirt with a drawing by your children?
I would.
Would you proudly wear a t-shirt with a photo of your pet?
I would.
Would you proudly wear a t-shirt with the logo of your employer?
Hmm…
We spend most of our days living with ourselves, our partners, our children, and our organizations. And maybe a dog. Or a chinchilla. A happy life should include feeling happy about the relationships that you maintain, with yourself, your spouse, your kids… and your colleagues. (And your chinchilla.)
I call it the T-Shirt Test. An organization passes the t-shirt test when employees will proudly wear a t-shirt with the company logo on it, hoping that other people notice the name of the organization. Hoping that other people say, "Wow, you have a chinchilla? you work for company X? That's so cool!"
When your colleagues don't care to associate themselves gladly, in public, with the image of your organization, you might have a problem.
Are you wearing the name of your company?
