By accident, this week I discovered a very useful website. It contains a series of podcasts at a website called www.managertools.com. From the site you can get weekly podcasts on manager tools and on career tools.
The two guys, Mark Horstman and Michael Auzenne, provide very interesting conversations about simple practical approaches to a set of work challenges. The management tools podcasts include the use of one-on-one meetings with staff, and skills such as delegation and feedback.
As well as the podcasts, there's a blog and a range of other resources.
Have a listen. I am sure you will find their ideas useful and stimulating.
