Answer 2

I believe the answer is: Firms might maximize revenue by raising price or output

When a firm higher an additional worker, the total labor expense that they have to spend would rise. 
But this situation wouldn't reflect negatively on their income report if that additional worker could contribute to more output that has more value than the cost of his/her employment.
