How do I know if I'll like a workamping job?
These are questions that only experience can give you. You might have had the same trepidation in your other career(s). How you dealt with it then, is probably a good way of getting your answers about a workamping job.
After talking to the recruiter, ask to talk to the Area Manager or local supervisor. If possible, talk to people who have worked in the campground, for the management company, and for the local supervisor. Understand that different personality types will have different experiences. So it's important to get information from several sources and try to get details about their pros and cons. Keep your own list of pros and cons so you can try to discern how you would deal with them.
Although the monetary compensation for workamping is generally low, it is supplemented by a free campsite and possibly some utilities. If you enjoy living in your RV where most people only get to visit for a few days, the benefits can be very fulfilling. Breathing fresh air, watching a huge variety of wildlife and enjoying nature as seasons change from Spring to Summer to Fall is very refreshing.
Of course there IS work involved. Many workamping jobs are pretty physical and can include: bending to pick up garbage, mopping restroom floors, shoveling out fire rings, painting signboards and restrooms or moving rocks or logs out of campsites. Dealing with the public can be mentally and emotionally challenging at times. Most campgrounds encourage a family environment. There are techniques we can use that discourage troublemakers from staying in our campgrounds and disturbing the peace. But if your general attitude is that "most people are not very bright", this isn't the job for you.
As you look for your first, or next, workamping job ask every question you can think of and do some online research. If you're not sure about a particular job offer, keep looking. If you are hesitant, it's probably for a good reason. Wait until you find the job that feels right. But don't expect the recruiter to hold a job for you for too long while you decide. There may be others who are interested.
