Returning to work - I had a 20 year IT career with heavy emphasis on mainframe technologies
I have been out of work for a number of years due to being a caregiver for an aging parent. Prior to my absence, I had a 20 year IT career with heavy emphasis on mainframe technologies ( cobol. Db2, IMS) as well as some client server experience.
I was wondering what courses or technologies that I should take to make myself desirable to employers? Not having anything current on my resume is a hindrance to finding employment.
