Marina imagines that if she leaves her employees unsupervised for even a few minutes, they will do nothing but slack off. She is
known as the "Dragon Lady" (well, not to her face) for the harsh criticism and punishment she disburses whenever an employee makes an error. Marina is a __________ manager.
It is clearly stated here that Marina is a Production Manager, as this job requires overseeing production process, among other responsabilities. In this paragraph it mentions "whenever an employee makes an error" "unsupervised they will slack off" so that means that employees here produce somenthing which needs to be supervised by the Production Manager.
As per the given description, Marina would be characterized as 'theory X' manager as she displays a pessimistic point of view about her employees(which is reflected by the phrase 'if she leaves her employees unsupervised for even a few minutes, they will do nothing but slack off'). The unpleasant title was given to her as 'Dragon lady' due to the harsh punishment and punishment that she displays towards her employees shows that she naturally considers them to irresponsible and unmotivated towards their work. Therefore, she would be characterized under the theory X category of managers.
