brownboss,
How many managers and supervisors at the building where you work have you had this discussion with? What did they tell you? If you have not spoken to them, that is where you shoud start. You said that your main reason for wanting to get into managment is because you dont want to drive. That answer will not get you promoted. You need a better reason than that. You will be working with drivers all day long as a Business Manager so you need to know the driving job inside and out and have an appreciation for what that job involves. You also have to demonstrate success in your current job before moving on to another job. Do you have a degree? You will most likely need a degree to be considered a candidate. I recommend talking to the supervisors and managers in the building you work for to get their advice. They know the opportunities that are available and know which people you need to talk to.
And yes, if you are a candidate for management, you are always "on" so be professional at all times and skip the text message grammer, the bold font and incomplete sentences.
