I was hired here as Admin assistant with IT skills in my current company, i joined them in nov 8 my probation period is over after some time they asked me why arent you doing any work i said i have finished my tasks. here is very little work, they said okay they put me in sales work with the sales guy, and told me you will replace him when he will go on vication i didn't have any choice but to sign else they would have fired me, now i have offer letter for 6500QAR currently they are paying me 3500 qar. i give my HR the resignation paper he said you cannot go you have 2 years of contract and also you have signed the replacement paper. i said i will resign on portal he said QUOTE AND QUOTE A lot of bad things will happen to you..

i have worked very hard for the new postion if anybody here is with some power or a QATARI or whatever can help me please DM me.

i have resigned and texted HR on whatsapp along with the picture of resignation paper that i have given you the paper and my notice period starts from now.
