Working over the weekend

Sometimes I had to work over the weekend. Do you have to work over the weekend?

My work is related to provide some training and coaching for the coperate executives and managers.

Those people are very busy to operate their works on weekdays but they can spare time for learning over the weekend.

Usually people who are willing to attend those learning opportunities are very highly motivated and enthusiatic.

But this weekend one bid different.

Only one of them was very enthusiastic for learning but the rest of the group were not.

Those kind of situation I hate most, no questions, no interests for learning.

They spend two days giving up their holidays to come over the workshop to learn new stuffs to help their works.

Well, I put 100 % energy for it but I couldn't get any reactions.

I have to learn more about how to motivate the people even under this kind of situation.

Sound like tough but I will try.
