Pros
Management will try to provide you with hours that are within your listed availability. There are opportunities for even the least qualified to move up because of terrible turnover. All you have to do is show up and they won't fire you.
Cons
Working in healthcare presents the opportunity to see many things that workers in food service and retail aren't used to. This includes viewing patient wounds and entering & operating vehicles owned by people that can only be described as hoarders. This is a job designed to fail. While the company may be able to adapt into more markets and open new types or positions, the valet market is going to disappear in the next 35 years. You have to work your way up quickly or you'll be out of a job. Hot or cold, you are expected to withstand inclement weather scenarios and proceed with business as usual which includes standing outside, running, and faking your best smile while operating the vehicles of strangers. Management only cares about your health if you are considering filing legal actions protecting yourself. Pay is abysmal. I would rather work fast food. Some sites pay as low as $5 per hour and if you exceed a certain amount per hour in tip make up it is subtracted from your paycheck. People that go to hospitals and use free valet always seem to not carry cash, or say they will get you next time. You will be constantly scolded about your poor mystery shopper scores because of the incredibly high standards set, especially so when you are shopped on days when you are working alone and unable to conduct service in a timely and organised fashion due to the nature of the poor work environment tugging at every last bit of your sanity. Valet guests are incredible painful to deal with. They are entitled and see you as an object. Less than half will tip you and it will mostly be coins or one dollar bills. Benefits are so expensive that you should only enroll if you would rather have dental insurance than a place to sleep at night.
