starting to hate amazon slowly

So I had an incident with a manager & basically I told one manager I was going to the break room to take a extra few minutes on break he said ok do your thing cuz I had a family emergency going on I had to answer my phone. a different manager comes in & is like oh you need to be clocked out while on my floor snapping & giving attitude about it. so long story short day goes by smooth we have a man to man convo about it then have my days off comeback to a write up for it basically saying I was late 6 minutes from break when I was talking to the manager & the other one knew what I was doing & said ok I opened a case against this guy. ive been working my ass off here ever since i started 2 months ago but i don’t know how long I can continue if they don’t see my good work & only see the little bad shit. its so strict at amazon makes me feel like im in slave times or something its evil here & i dont like it especially a guy who comes from cutting trees. Mind you I got the write up 4 days later came back from my days off to that dumb shit
