EDIT: It appears it's a two-to-Tango issue. All the cases mentioned are with another party involved, and whether it is to incite emotion or prevent it (i.e. e.g. hiding an aggravation as a flight attendant), the emotional work being done is within the subject itself.
It could have some part of emotional labor. It's hard, you have callouses on your hands, it's hot, your cloths are all dirty and sweaty, your co-diggers criticize your digging speed. You want to cry, you want to stop. You do emotional labor to keep going.
