What if you were hired for a job that you weren't qualified to do? Imagine the stress! Each time you were assigned a task, you would try your best, but your best wouldn't be good enough. Time after time you would fail. You would realize that it was only a matter of time before you were fired.
A common scenario in my workstation where most of my colleagues don't even know a thing about the job they were hired to do. One bad ('coz it isn't good) example, a recently hired high school graduate, who lied on her resume, and since then keeps pretending she knows the job she is assigned to do. It normally takes her a day to finish a very, very short business letter, and at the end of her pretend day, she would say, she's dead tired because "wajid shukuul" (too much work) ugghhh!!!
Just venting... ha ha ha!!!
