Wow!
I love this. Sincerely, I like how you wish to dig into the root cause of your fellow worker's unseriousness and lack of productivity. This could be caused by anything — low motivation towards work, poor work culture, managerial issues.

You'd make a great leader ke akpaniko. We often need leaders who dig deeper than the surface area to understand the actual issue and profer solutions. I wish you all the best!
