A word to describe "John."
John clearly did not want to paint the house. He clanged the paint cans and noisily dragged the ladder around. The painting was quite sloppily done and the edges came out uneven.
For example when told to clean up or to do some other undesireable task the actor performs the job loudly. Possibly that person is loudly sighing or performing noticeably poorly within earshot of others so that all in the vicinity will learn that the actor does not want to do what is asked.
Maybe if told to put something down that person slams it down. Or if directed to drink a medicine they spill some intentionally. If the task is prolonged there will be muttered complaining or grumbling.
Not merely reluctance, but a word that means signalling reluctance.
To clarify: there is not an avoidance of confrontation implied here. In fact such behavior could quite easily lead to conflict.
