I think it's not wrong to start a job for training pay then quit
What is the point in training and then just quiting.
I found a different job that I want to do.
Taking a job in order to get a quick paycheck without any intention of committing yourself to it is wrong. It costs money and time for an employer to train someone. They shouldn't invest all that into someone who has no intention of staying.
I'm just thinking about making a better living, you can't blame me
You are just really putting the company at a disadvantage by doing something like this. I guess you do need to think of yourself at the end of the day, however just know that this is a pretty immoral move on your part.
