I feel you. Trying to train new people to actually do their jobs properly, being told that "they're junior, they'll jump ship in 18 months, don't bother. we can just use them as grunt-work people"

Then getting chewed out as a time-wasting perfectionist who blows deadlines because I'm basically redoing all their work in QA.

Then getting chewed out for not wasting even more time by sending it back to them once the boss tried to QA their work and shock! It's not great! Because they're not fucking trained!
