I do feel your pain. Are you saying you don't expect management to change their behaviour? If so, as long as your program is at least as good as the current one, they may not give a darn how good it is. That being the case, perhaps you should consider points like these:
How much easier would your program make your day to get through?
How much would you like to be able to modify the program thats in use? You will be able to if you use yours.
By putting your program into production, you gain experience you can put on your resume
And maybe, just maybe, you'll get that recognition you're looking for.
It may be that the only group your program benefits are you, and your coworkers.. but maybe thats good enough. Recognition doesn't always come easy in the workplace. However, the good 'ol Peanuts characters have some excellent advice for us all:
Lucy: "What happens if you practice the piano for 20 years and then end up not being rich and famous?"
Schroeder: "The joy is in the playing."
I've kept that quote in my email signature for awhile, you've reminded me to add it to my signature here :-)
Not everyone has the opportunity to put a program of theirs into use at their workplace. It can be a really good feeling to see your own code hard at work, even if you don't get a raise for it. Good luck!
