Pros: great pay and benefits, some of the people, learning new skills
Cons: overmeddling hr department, lack of direction and decisiveness in management
I worked in the radio shop in an open pit copper mine, which was usually dusty, especially in the summer and would turn into a quagmire whenever there was heavy rain. I had to board electric and hydraulic shovels sometimes and there was thick grease everywhere that I had to be careful not to get on my clothes but sometimes would anyway.
I learned about the Motorola MOTOTRBO trunked radio system as well as mesh networks and computer-based instrumentation systems. I liked the radio programming and computer networking and configuration as well as man basket truck operation aspects of the job the most, new equipment installation and daily preventative maintenance on heavy equipment not as much.
