Pros
Great pay, training, and benefits for Union positions. Management positions receive ongoing training and there is a good support team. In the Union positions you have the opportunity to make really good money, even without a degree. For consultant/customer service type positions it pays 20+ per hour and overtime is typically available. Verizon is huge on compliance and training, so you'll always be up-to-date on what you are selling. (I've worked for other TELCOS that just gave you zero training). Plenty of room withing the company to move around and into other positions. Great incentives/awards for excellence in sales, etc.
Cons
Union positions pay well but policies are not very flexible. Taking a management position is pure hell. I started off as a Residential Sales & Service Consultant. Though the pay was excellent, I found the work repetitive and I wanted more challenges so I took a promotion to Team Leader. This promotion was ill advised as you become hated by the Union employees and beaten down by Mid-level management. You are always struggling like a juggler to keep 4 balls in the air.. while getting kicked. I eventually took another promotion/lateral move to become a business sales rep that was for less money, but allowed more freedom. I eventually took a management buyout and I now work for AT&T.
