If you don't have a life and enjoy worrying about your job stability, join the OSI team.
Pros
Core is a great product with ongoing creativity for development, albeit limited. CEO is advocate for clients. Employees are the best of breed and really great people. It used to be a great place to work with a family atmosphere.
Cons
Other products purchased through the years are not developed. Financials are questionable, service and product development stripped down to just get by. Consistent reductions for many years, ongoing. Employees don't feel secure about their future are are overworked. Unless you are "in" no opportunities. Regardless of delivery or years of dedication, you are "let go" without trying to find another area where your expertise could be used. Worked long and hard hours, including nights and weekends. Road Warrior is putting it mildly. No contribution to 401k. Needs to be purchased by someone who cares in order to go to next level.
