re: Automate Your Way To One-Day Work Week
It seems to me automating repetitive work, coming up with IT solutions, and the reduction of staff is what CIOs and technology have been seeking to do for years. His coming forward may disappoint some of these CIO/CTO/Business Analysts that are pulling down big money, but he may also find a method to market his discovery and make more than the bonuses if it turns out to be a sound, validated process (it may be making errors noone has yet identified or bad calculations). The fact he is taking the lion's share of bonuses with production far superior to his workmates should have raised flags to management to find out exactly how (desiring to transfer the knowledge to the others if it is process related). One employee once increased his salary by playing online poker but senior management held him up a brave, chance taker personality they needed more of.
With regard to the ethics question, toward his colleagues noone apparently has limited how they do their work so I see no violation toward them. Toward his employer, he was hired to do a job which he is doing and they seem less than interested in how he is achieving such performance (there are more than one may think out there that are afraid to ask the question for fear of the answer). I would like to say this would seem uncommon, but I have seen it in Europe and in large US corporations and the conduct does not seem that odd. If this has been going on for years, he may have good reason to fear a vendictive company response if they feel they've been taken all this time or lost productivity across the board.
