Nothing is a given in the workplace.
If you want security in your position or if you want to move up, you'll need to put into practice some habits that'll solidify your standing. That is, save money for your company. Check around your department or your position and find ways you can change the status quo to save money or make yourself or the department more efficient. The most valuable player in the workplace is the person who knows how to roll with the punches. Let your boss know.
