I make lesson plans for a small education business. It's small enough that my boss is the owner of the company and tends to directly contribute and make changes to these lessons. My problem is that a majority of the time, his changes significantly reduce the quality of the lessons and overall make things harder to teach. I'm really passionate about my work and he understands this to some degree and avoids working on projects that I'm currently in the process of creating.
At first he used to run any changes by me, but my opinion on them was almost always negative, so I think because of this he's just started working on things once I'm done with them. For example, I recently came back to a lesson plan I hadn't looked at in a few months, and it was awful. I wish I could show a comparison of before and after his changes as evidence, but that's definitely outside of my NDA, so just imagine slideshows that are intended for children covered in small, detailed text and you get the idea.
In the past, I've let him do these types of changes and just tried to let it go, since the amount of issues is usually so substantial that it would be hard for me to politely recommend more than just completely removing his work. The problem is, he now wants me to do some work based off these modified lessons, but they're so low quality that it's genuinely upsetting to try and work with them. I've truly been struggling to do any real work because every time I look at it I just get frustrated and want to fix it or quit.
I know he trusts me to some degree, it's why I'm in charge of this program, but at the end of the day he's my boss and I feel that I can only say so much before I push things too much, and I already have a ton to say.
