me VS my supervisor and my manager

ive been working now for almost 4 years in the ministry of state for ******* ******** , i worked really hard more like dedicated to work, i was and still better than my other colleages , do this do that and dont do this and dont do that and im like inshalah, i wll ,i wont, inshalaah .

and what do i get ??

a month ago my supervisor screamed at me infront of all the other employees for something i didnt do and she keeps on insisting i did it and takes it to the manager , she forgot all the good things i did and blames me for a mistake another supervisor did HAHA i dont know whether to laugh or cry .

ofcourse the manager is on her side :@ coz she does whatever he tells her even if it was WRONG , i got mad so i fired back and started crying and screaming at them at the same time ( aanaa 3a6etkom wayh wayed . kel shay tabona asawelikomya bla bla.. etc.. etc) argument lasted for an hour then everthing went back to normal

ever since im a rebel , not working as hard as i used to , i come to work late and leave early , next week im taking a long vacation and after this vacation im coming back with a note says (SCREW YOU I QUIT) . lets see who will do theire job now :P

moral of this story : work hard and get blamed , dont work eat 7ab and drink chay and ull definately get a raise
