My job is support (Treasury Assistant) at a pretty high level in a large private company. One of my bosses (I have two until one of them retires) insisted that I take a business law course. The course, it turns out, does not cover what is actually relevant to my job. In addition, with my terribly low energy, and so many bad days so often with this recent diagnosis of Crohn's, I have stalled halfway through and cannot finish in time.

I can get an extension, which the company is willing to pay for, but I know that the next 18 weeks will be no better for me to finish the course.

Ultimately, my heart is not in it. And with such limited energy resources at my disposal, I want to use them in more positive ways for myself.

My question:
What is my best approach for letting my bosses know that I will not complete this?

I'd appreciate any views on this!

Thanks!
