We have a ticketing system with multiple levels of importance, levels 3, 4 and 5 are in common use. Level 2 people get paged, and if the ticket isn't addressed quickly the pages rather quickly escalate to VP level. Level 1 and the executives get paged, it's only supposed to be used in situations where the company is losing large amounts of money quickly. There are multiple prompts attempting to alert the user what they're about to do, including one that flashes "ARE YOU SURE?"
We had a security guard who got annoyed that the access he had requested hadn't been granted in 4 hours (SLA is 6), and escalated his ticket directly from 5 to 1. The CEO was not amused, and his employer almost lost the contract for guard staff the next year.
A programmer left and created a Level 1 ticket saying essentially, "Hey, I've had a great time the last five years and learned a lot, now I'm going to a new job and just want to thank everyone responsible." Something like 150 people got paged, from the CEO down.
