"I mean seriously, if you can't understand how an email list works and you work at a technology company, something has gone terribly wrong."
You'd think that, but no, it's quite normal - not everyone in a technology company is going to be a tech expert, not everyone in a pharm company is going to be a chemist - you get the idea.
But I can do one better. I used to work for a company that was about 250 employee large, and we had to run a process on every computer that took about a half hour. Not hard, just time consuming, and obtrusive to the users.
So we took the obvious path, script the bloody thing over the weekend when everyone is out. To this end, we send a building-wide email to all the users explaining they should leave their computers on over the coming friday, for the half hour process to be done automatically on saturday.
We received about a half dozen strongly worded responses that if it only takes a half hour, the computers are going to be needlessly on over friday night, most of saturday, all of sunday, and through to monday morning. Obviously a bunch of greenies.
At this point, you'd be thinking "so what".
Well, this is so what: The company designed and commissioned coal and gas power stations. Each and every employee there to some degree contributed to what the company did. Including those half dozen greenies who obviously didn't look too carefully when they applied for their jobs. Clearly, when reading the dictionary, they missed "irony".
