Ever been 'promoted' into a new role with only a small salary bump, and an inability to hand off your old role to someone else?
Or perhaps you are a driven/smart person. Which management rewards by increasingly spending your attention on various areas of the business that need to be rescued, organized, straightened out. Yet management drags their feet on any permanent changes which would prevent the fires from starting in the first place. What begins as a rescue operation gradually becomes normal practice. Over time agglomerating your responsibilities across various critical areas.
Job postings like these are what happens after you leave.
