What message did the foundry workers and the new engineer convey to each other through their non-verbal behaviour?

The foundry workers conveyed a sense of distrust and skepticism through their closed body language and lack of eye contact towards the new engineer. In contrast, the engineer's open posture and attempts to engage with the workers indicated a desire to build rapport and establish trust. However, the workers' hesitant gestures suggested they were not yet ready to embrace the engineer's intentions, highlighting the tension between their established practices and the engineer's new ideas. Overall, their non-verbal cues reflected a clash of perspectives and the need for mutual understanding.
