Is There Any Reason...

I wonder years later if maybe he was hoping for a chance to file an ADA lawsuit, and when I didn't fire him right away that is why he quit shortly afterwards.

Color blindness does not work like that. Color blind people can still see colors, they just have problems with some specific colors or color combinations. The most common variety is the red/green type. It makes it difficult to tell the difference between red and brown, and also to see small red objects if they're surrounded by green. Finding cranberries, for example, is nearly impossible.

If he was consistently mixing up, say, orange and brown, it would be plausible that color blindness could be the issue. But if he was even mixing up the white banded wires with the solid color wires, then color blindness is not the (only) issue.

So, yes, there must have been something else at play here.

"service economies" tend to develop these ways of "making the money flow". Makes manufacturing ever even more impossible.

In Britain we are about 10% of the population (9%?), so the 90% will want things which keep meals appearing on their tables. So there will not be a "survival" aversion to this sort of thing. Can understand that

- next meal on the table; keep it coming; go meal by meal. In any "service economy" money wells-out of a hole in the ground somewhere beyond your sight and washes across the economy and you grab your bit of its flow.

--------------------------------------------- During the development of Power over Ethernet I wrote a complex program to configure the controller ICs which included color to show status. A color-blind engineer couldn't use it so I made the colors user selectable and he found a combination he liked.

My uncle Doug (RIP) used to get a ticket almost every time he drove thru Preston Idaho . He had red/green and the traffic lights there were reversed from the pattern he was accustomed to .

-------------------------------- A fundamental of socialism is obscuring cause and effect so those in power can deny responsibility and shift blame, for example our current shutdown.

That well is pretty deep here but noticeably diminishing, especially from Bidenflation. I am aware of the loss of manufacturing because I attended the closing auctions to buy home shop machinery. Since the 80's producing the items that I prototyped in the USA has been declared impossible.

The demand for real vs artificial 'fiat' value has driven gold and silver prices up dramatically.

However US currency doesn't have to be accepted for payment, despite the "Legal Tender" claim printed on it.

And so are their suppliers.

The dream of releasing people for more "fulfilling" work by automating factories, and taxing the output of the machines, has either been bungled by incompetent leftist economics or wouldn't keep us strong anyway since any poor country with a largely uneducated rural population could adopt it. I have a 6-jaw lathe chuck from Outer Mongolia and electronics from Laos.

At the time of the question, did he know the job required him to identify wires (or anything else) by color pattern? Could he have possibly thought he'd pull the cable and somebody else would connect it? They are at least somewhat different skills, the former more labor-ish and the latter more electric-ish.

--------------------------------- I have never been asked if I was color-blind when applying for an electronics technician job that required reading color codes.

My dad claimed blue/green color blindness kept him out of the pilot program in the USAF, but he could accurately distinguish many shades of blue and green.

I don't recall exactly which wires were wrong, just that they every jack was wrong and not the same each time. In Cat 5 twisted pair you have 4 pairs. White/Blue, White/Orange, White/Green, White/Brown. The whites are typically mostly white with enough of the other color dashed or striped along them to easily identify, but the big thing is the white is twisted with its corresponding pair mate.

The twist is to reduce noise and interference and with Cat 5 (unlike telco) it has 5 twists per inch, making it nearly impossible to accidentally un-pair the pair accidentally. Telco is twisted, but at a rate that can allow the pairs to fall apart when a loose dry cable jacket is removed. I don't think anybody uses telco for new installations anymore. Even analog tends to Cat 5 or better to facilitate future upgrade to VOIP.

I didn't really think of it at the time. I was just glad he quit. The thing is on my aptitude test (people didn't have to know the answers, it was just to determine of they were lying on their application, and how much I would have to train them) he did know the color pairs and their order.

Reminds me of a story I heard from an alarm co owner who did a security system in a federal law enforcement building. Every conductor had a white jacket, and no conductors were allowed to be labeled. All devices were tampered, so they couldn't identify any conductor without triggering the system. As long as batteries were good you couldn't even power it down without triggering it. All they could tell was these conductors coming out of this device went to this device. Yes, I know about piercing probes. I've used them. Heck telephone tests sets have them by default. I have 3 or 4 good ones still around somewhere.
