I'm not going to do my job
What kind of job do you have?
I'm a research assistant at the University of Barcelona.
It seems like you don't enjoy it, but you will get fired for not doing your job.
They better fire me. Then I will sue them and make money myself.
If you don't like your job, you should quit. You won't have a legal case if you get fired for not performing your responsibilities, and it will only hurt you in the long run when applying elsewhere.
