Unless you love being told "no", stay away
Pros
For a person starting with Hertz (Manager Trainee) the good part of the job is the weekly paycheck. You can also make some money for overtime as well as your bonus if you make your sales numbers. Also, if the branch is profitable, you can get monthly and quarterly bonus. As others have said, being able to drive new(er) vehicles is nice. If you can survive long enough to get a location manager position or above, you then have vehicle privileges which means you get to take home a company vehicle every night.
Cons
The downside of this company. When you work at the local edition branch, you must always make your sales numbers for their optional products. To do this you must follow the Hertz script verbatim every time, for every rental. You end up sounding like a robot. Further, you are watched by upper management to make sure you don't go off script. Managers must watch the Manager Trainees on a portion of the rentals they do and write up and verbally go over the rental with the MT. And not just until the MT has a good grasp of what they are doing, it has to be done multiple times per week, it continues forever. When a customer tells you no, depending on how they said it, you have to come back with a canned response. When the next customer comes in, if they decline in the same way, you give the same canned comeback. And if you don't make your numbers long enough, you get your walking papers.
