Emotional Labour - How to appraise it?

We could have witnessed receptionists shimmering with a radiant smile always!!! I have wondered on the plastic smile fixed in certain faces. The service industry workers throw us a positive vibration with their expressive welcome!!! All those are forms of their emotional labour. Many wonder if such emotional labour cud b appraised quantitatively. I think it is possible. Have u ever come across a situation where u met with an inconvenience, but still managed not to complain? Hope everyone of us would have done that at some point of time in our life!!! Reason? We might have got some soft corner with the person who got us such inconvenience. What makes us hav such positive feel with an unknown person? The positive emotional feel is mostly because of the positive expression they pour on us. Their smile, welcome, poise attitude, etc.,
Hence the complaints we get against the service industry workers do play a major role in understanding the emotional labour of the workers.
