does anyone have experience confronting their employer about your responsibilities getting wildly out of sync with your job title? my title is supply chain analyst but more than 50% of my work is not supply chain related at all anymore. I'm being treated mostly as a data analyst. data analyst salaries are 10% higher than supply chain analysts salaries in my area plus there are many more job opportunities for data analysts. I want a title change.

also does anyone have experience writing a resume when your responsibilities are not related to your title? should I just say I'm a data analyst because that's the work I'm doing or is there some special section I can add noting secondary work as an unofficial data analyst. there is other shit I do very often too that is barely related to either role.

anyone who has been following me for a while is gonna think I'm sooo late to this realization but it's getting pretty clear to me that my workplace is not going to stop pushing me into roles that I'm not appropriately compensated for, and because these roles are not official I will never receive any support, even when I explicitly request it. I have already been denied support multiple times.

this isn't just random people asking me to do one-time odd jobs either. our COO, CFO, and multiple directors ask me directly to do shit like investigate errors in our website and its tools to uncover what is causing data to display incorrectly. this is to shift labor off our web dev team and onto me, why us paid way less than a developer. I do NOT know ANY programming, I just know the database. this has happened five or six times now.

I also manage customer issues directly with the customers because our sales team does not appropriately train anyone in their department. I create orders for them too because they can not be trusted to enter them (not because they're untrained, but because they were not entering these intentionally). I provide records and reporting for accounting audits. I build weird calculators and generators in Excel for every department except two (IT and web dev) because those two can't justify devoting time to those projects and integrating them into our site. I create extremely weird queries to trace information that out database does not track appropriately (and this will never be fixed).

there are zero docs for anything I do except the ones I personally wrote, and only very limited notes scattered around. I was never trained and only picked sql and stuff up cause when I was a buyer digging into data helped me solve problems more efficiently. I have been begging web dev to tell me when they update anything because they keep breaking extremely serious tools but they have been ghosting me entirely. literally all they have to do is CC me on update emails but they won't do it.

also there isn't anyone else in the company who is proficient in sql and stuff (outside dev, and they're miles above me) to back me up so if I'm overloaded or need other help I'm shit out of luck. this makes taking PTO a fucking nightmare too because I'm always in the middle of helping someone out of a fucking fire and everyone does that shit where they say I can take PTO any time I want without worrying but then constantly assign me with critical tasks and demand results asap.

It is beyond time for me to be realistic about this job and what I want to do with myself 40 hours a week until I die, so I need to start working toward either making my current situation more tolerable or going elsewhere.
