Phase of my work i am hating right now.

I am a budding s/w developer. Out of my curiosity and zeal to learn and to sharpen my skill i built a product delivery framework for the organisation I worked on contract for the past 2 years. Which somehow went on to have a bigger impact on the organisation's product delivery timelines. I thought I had accomplished something today with my ability but then came a shock to me. My reporting manager who i used get approval for having few permissions from the upper management for implementing such a framework has procured the documentation of the framework and pitched the framework among the pm as it was his own idea and effort even he changed the documentation author to his name( that org hardly writes docs for their products) and pitched the framework accross the org and got all the appreciation without putting any effort into it. This is a great learning for me and a good experience for the people who are reading it. My advice to young s/w engineers whichever org you work your idea and thinking will be fresh and innovative It's better to save your idea and effort for the later stages of your career in the org once you get some sort of ownership on what you work so that you can't depend on your levels who just approach you in the intention to steal your efforts always. True hard work always has a reward. You thought I was ending it here but no . I had plotted plans to screw him over stay tuned...
