Pros
This is an excellent choice if you are planning to only stay at the company 2.5 years. If you are on the Fortune 500 career track of switching employers every few years, you cannot ask for a better place to work. It is such a mess that you have the ability to easily convince the management of the next big idea. They are grasping for these types of themes. By the time it is implemented you can be on to your next job. For those who are offered a job - focus on base salary. Do not get caught up in promises of bonuses/commissions. The executive management will change the plan if there is a risk that they will not make their bonus. You want as high of a base salary as possible. Bonus/commission should strictly be an after thought.
Cons
This division of Western Union is such a mess that it is very possibly going to be sold. My guess is to private equity. So if you have the flexibility to get in and out, it would be a wonderful feather in your resume. Some think a con would be the management, but that it actually a pro in this environment. You simply must do what they say without question and praise them. Concentrate on a high base salary. Do not accept promises of future raises and large commission and bonus. They do not materialize. What you get in your initial agreement is it and get it in writing. You need to go into this environment with your eyes wide open. It should be viewed as short term. If you are a person who cares deeply for what you do and your clients this is not the place for you.
