Will you accept that condition in case you want an increase in your salary? Your colleague at work is being fired in return adding his salary to you.

Do you mean that your company found out that it needs only one chemist instead of two and comparing to you colleague you were found to be a more valuable addition to the company?!!After all no sane company fires a qualified efficient employee unless he becomes a burden! And if that's the case you can't blame yourself for his laziness!!
