rictus, dude...you fired yourself.
you didnt do what you were told at a job because you personally disagreed...just cause you felt you didnt have to.
their grounds for termination are valid and just, you fucked up
You can try and appeal but you sealed your fate by not giving a shit and doing what you wanted
i dont mean to sound harsh man, but its your own fault. depending on how long you were there you might want to also leave them off the resume or future application. your reason for termination isnt favorable and would only harm you.....the gap in employment can be explained as "helping a sick relative"
honestly you should learn from this...and turn your stumbling block into a stepping stone.
good luck in the future, this economy is a bitch
