Have you ever had a job where you were told you’re “too slow’ ?

I have been a night shift stocker at a grocery store for the past 2 months, since I’ve been there 3 guys have been fired or quit. This morning the store manager has been saying I’m too slow and if I want to stay employed there I have to speed up. I do the job and I show up, that’s all I can do right? No more than what’s asked of me. I mean hell I’m paid by the hour what do they fucking care as long as it’s done?

I feel like I personally do a good job and that should be all that matters
