To my experience , the GMs are usually not the people who know anything about hotel management . They always have an Assistant Manager or Director of Operations or whatever you call the second highest position who does all the work . The GM signs papers and they try to look like worried about things they don ' t even understand . When my GM decides to sit in on our revenue meeting , we have to switch to a language similar how you ' d explain hotel shit to fifth graders so he can understand . And in the end , he ' s the one calling the shots . Their job would be decision making and nothing else . And they should hire people whose expertise can be trusted and base their decisions considering these suggestions . It ' s impossible to be an expert in everything but it ' s pretty easy to be expert in nothing . The latter one is usually the GM .
