Pros
If you're lucky enough to work in a branch run by a good manager who actually, genuinely cares about their employees (you'll be lucky to find many of those) you will learn a lot about the fundamentals of how a business is run and you'll likely be part of a great team of people within the branch. It would also be unfair not mention the fact that you will make a lot of friends at Enterprise and you will be surrounded in your branch by like-minded people.
Cons
Firstly, the hours are beyond ridiculous, when you apply you'll be told that you'll work around 50 hours per week, add at least another 20 hours per week to that! This consequently means that you will have no life. You might as well say goodbye to all of your friends, family, gym memberships and normal sleeping and eating patterns. And the best part, you'll probably not get paid for working those extra hours either! During the recruitment stages, Enterprise put a lot of emphasis on 'future leaders', once you start at your branch you'll soon realise the managers (about 90% of them) are far from leaders, all they care about is money and they will make you do all the work so that they can sit in their office and take 3 hour lunches while you are lucky to get a 10 minute lunch break. There were so many instances where employees have been in car accidents whilst working and the only thing the manager will ask is "Is the car okay?" don't even be shocked when they don't ask if the person is okay! You are essentially a glorified taxi driver who cleans cars in their suits. Not only are you put in a number of dangerous situations, you're made to clean cars at 10pm at night when you started your shift at 7am. I could go into a lot more depth about this, but I don't think I need to. Honestly, you've just (or probably recently) completed a number of years of university, a dissertation and a lot of stress, but you are worth a lot more than this company. Yes, this company does provide opportunities for promotion. But during my time working there, I don't think I've ever been so down, sad, demotivated and upset. I suffered a number of health problems due to the stress that I was put under in this job, and by no means am I someone who is afraid of hard work and long hours.
