I've automated a couple of small processes that are used by several people. And I've also added some pretty solid error-handling in our automation code in order to automate a pesky app that has a very brittle UI.
And while a few people are appreciative of my efforts there are a few who're constantly trying to pull me down or belittle the work.
This question is NOT about deciding whether or not the teammates are trying to hold me back. For the sake of this question, please assume that there are teammates out there in the world who try to hold back their colleagues' performance.
And that they're repeating this behavior over and over again - trying to find faults or pull down my work in some way or the other whenever I've done something good. Always trying to find some way or the other to criticize but never appreciating anything I do or say.
I find it difficult to send out an email informing people of the new feature/tool that I've created because my stomach hurts at the backlash that I'm going to get from these guys.
How do I deal with teammates who keep trying to hold me back and bring me down while I'm going the extra mile?
