This shit is why, when banks announced they were going to stop processing physical checks and a whole wave of elderly folks protested, I understood. It's one of the last fleeting vestiges of anything in their lives that still makes sense, and arguing about the cost of supporting obsolete systems is an absolute red herring.
It's not about the money. It's not about the tech. It's about kindness, and being fucking human to each other.
Do you work in IT? Do you support a system? Do you work on a helpdesk? Do you take calls, answer emails?
Congratulations. That's no longer your job title. From the moment you read this, you're a user advocate.
Process issue holding something up? Bug in the app? Is a particular system always down? Advocate for your users. Go to bat for them with the teams responsible for their struggles.
Folks will say "oh thank christ, it's you" when they hear your voice on the phone if you advocate for them.
