Maybe to help handle the problem at work where they want to make you a supervisor, it would be good to work out what you need to say to them by reading a book like “Asserting Yourself” by Bower and Bower.

That way, you could get your point across about not really wanting to be a supervisor without upsetting the bosses and this could help you to stay in your current job which you like.

This book and the others I mentioned could be ordered on the Internet from such sites as Amazon or Barnes and Noble for example even if they’re not based in the country where you live.

I hope this helps.
