It's not.
More than a union "thing" it's more of a "brotherhood" thing: You burned the crap outta (or killed) my buddy, yours is gonna be the LAST service restored.
You can then expect all manner of "fun and games" from the utility's legal department, just for starters. They WON'T, however, "never" reconnect the service. They'll just bury you in so much bullsh*t following the accident that you'll hire a licensed unionist electrician to install a transfer switch
- and wish you had done so earlier.
I honestly believe that everyone participating in this contentious topic has the KNOWLEDGE and smarts enough to OPEN the main breaker or pull the meter. It's the plethora of clueless DIY'ers out there buying generators "just in case" that are cause for concern.
