first, your boss's back ground is not strong and second he is not that support uthat is not a difficult to explain situdation and your boss just need to make a general statment like: well, i understand the situation and felt that is not his fault. (very strong statment) first ...(that reason for the cause), second ...( due to some urgent work, u did not get time to prepare)...third, to be fair, even in school, you need time to prepare your exam......(make it to be a general fact that most people will fail under this situation)...
and your boss need to be strong in making above statment...then no one could use this to against you again....
or next time u could make above explanantion if your boss just hmmmm....but a lot risk lah......ang good luck
it's true that my boss's background is not very strong
he is just promoted to manager level recently. Besides that, he is disliked by many people in this company, including many people under him. the turnover rate in the department is extremely high...around 70% old staff left in the last 12 months. The only reason he has his chair in the meeting room is the performance of his projects.
