I'll just continue to grind in this job until I get fired, die, or hopefully can retire someday (maybe coastFI).
I like to learn new things, struggle (within reason), and iterate on my previous attempts or prototypes to build a better product that I can be proud of. I did this when I was building my android apps and loved it.
My problem is that the company sets us up for failure and doesn't even realize it. The business consistently gives us terrible requirements. They can't build a business process map or anything else to describe the processes they follow. They constantly miss big pieces so we end up with systems that are spaghetti code to cover all these things they miss.
The company also views struggling with new tech or roles as a negative. They don't provide any real training either, but I guess the Plural Sight self-learning trend is more of an industry thing. I joined my new team about 4 months ago and worked on a AWS Lambda in Python, Slunk alerts/dashboards, Tableau dashboards, and I have no training in any of it. I had to self-teach AWS (2 certs), Python, Splunk (User cert), and Tableau. The demoralizing part is that little of this seen as valuable. I can't improve my career by "developing" Tableau or Splunk dashboards. I need to have a steady diet of AWS and Python where the requirements are 90% there so I can architect and develop elegant, or at least practical, solutions to an interesting business problem.
When you say self-teaching you mean you're paying for certs/doing on your own time? Or work is paying on one hand but going out after it isn't seen as valuable on the other? I'm just curious but by no means am I saying that there's not just bad situations to get out of, just that discomfort and feeling like you're not doing well aren't _solely_ reasons to leave. Hope your situation improves though, sounds like you're doing the work.
I guess the better way to put it is: would you assign Tableau work to someone who has no training or experience in it and then tell them they are taking too long? The only way to do it is to learn it as you go, which is going to be slower than someone who is trained. I really want to become an expert in something useful/marketable like AWS and Python, but these no-value assignments are throwing a wrench in that.
