As I was reading the dialogues I was thinking about the tone of voice used and definitely the second options are the most harmonising and the best to create a good working atmosphere and to unite the team. Those are the ones I would use, and with other words I have used something similar once.
The first options only provoke discomfort and distancing between the leader and the others. The work would be more complicated.
That's right, and while harmony isn't always the objective and is not always possible, a leader should know how to speak to each person individually and the team generally with the view to getting the best of them, uplifting and empowering them and providing support without removing responsibility.
As everyone is different, it is necessary to know everyone and to support them in the best possible way.
