The cross training will be a benefit to both of you. Companies these days don't care to see what cross training will do for their bottom line. I worked in the Bell telephone industry until I retired after 22 years. I went to work for a Mom & Pop phone company that was also a CATV provider. At an employee meeting, I brought up the idea of cross training the telephone techs & the cable techs. They went for it & it increased their bottom line because instead of two techs in an area to take care of service calls, there was only one.
