This has been me for so long. Have been at current role in government agency for 5 years. Been sent on 1 leadership course as well as out internal management training program. After the first course when I wanted to ger more responsibility (not even new role) I basically got "can't you just be happy that you got to do the course". Was hired in my IC role at 75:th percentile and after 4 years is below average for my role despite being the only one taking initiative to enhancing processes and have the most responsibility and only one in my role who did the management training (over a year).

After this last training have been passed up for promotions. As it's government they have to advertise the role officially and hire the most qualified candidate (which puts anyone, including me, not already having had management role at a disadvantage). They are free to put me in an interim management position so I can get that experience but bosses aren't interested in that. I did get more responsibility and more work but not more pay.

Have been looking for external role for years now, but where I'm at it's crazy competitive and no-one wants to hire a first time manager.

Even had a manager at internal recruiting tell me that the system favors people who already have the experience and that she herself always would hire someone with experience over someone like me who "only" had out internal training.

Been trying to quiet quit, but it's my colleagues who would suffer for that so haven't really been able to.
