Pros
Block is a good place to learn about the tax preparation business. The training is what you make of it...you can learn just about anything about taxes that is available. It is a great way to make money on a part-time, seasonal basis. It is fairly easy to obtain a job with the company - if you have management experience, it is easy to become an office manager. With hard work over time, (several years) you can create conditions where you are making a good amount of money ($10-$20k) in a realtively short period of time. (2-3 months) The pay is commission-based - with a draw that does not have to be paid back if you do not make enough to cover the draw.
Cons
This is not a full-time job. Only those who work in the corporate office, or who are District Managers level and above have the opportunity to work full-time. The initial hourly draw pay is poor for entry-level workers - for the first two years, it is much lower than one would expect. It is still not what you would expect for long-term employees and/or office managers. Because of this, turnover is higher than you would expect for a company this size. There is little incentive for entry-level people to return - could be a problem for Block in the future.
