i have to do this job, but i won`t. what should i do first???

Answer 1

Don't do it as you will be fired anyway if you refuse to do it.

Answer 2

You have it narrowed down to doing it or not doing it.

I think you should not do it first. You can then do it.

If you do it first, you've pretty much cut off your option to not do it later.

Or perhaps more detail would be in order.
