Pros
Freedom, you get to work on your own. You get to meet a lot of great people, if you do a good job. Also if you do a good job you will make a lot of money. I averaged 70k a year. The other reviewers probably did not do a good job, it is totally performance based. If you damage someone's house or do poor work you pay for it, if you do good work you get paid and even get tips, simple as that. I enjoyed the physical work, I lost 20 pounds in 6 months.
Cons
You have to work Saturday guaranteed and sometimes Sundays. It will be long hours but that is also based on YOU. When you get good, you get off earlier. It is rough when you first start, you will work a lot and you will not make as much money, that's how the cable business is. The better you get, the more you make and the shorter your hours get The other reviewer's comment about training and qualification is true. In 6 years i learned a ton about cable, internet, networking, and telephone but it was all on the job and not a single certification. They did not have medical/dental when I was there so i just got my own Blue Cross. Not that bad then but with Obamacare that would be bad now.
