Answer:
Zach is a sales agent who must place a grin to his face every day, regardless of his psychological state This requires a lot of emotional work because there must be a disconnect in his true feelings and how he must look to his customers.
Zach has to be emotionally intelligent in order to be competitive at his career. Emotional awareness is described as the capacity to control one's own feelings. He may be experiencing mental dissonance and not feel like smiling on certain days, but he must smile for his customer in order to serve himself well and close the transaction.
Zach cracks the bargain by channeling his optimistic feelings and incorporating a positive attitude into his jib. When customers are in a good mindset often make fast choices and buy the goods on sale. So, in his work at a pharmaceutical firm Zach spreads happiness and optimistic feelings.
