I (Marshall) started my career in floating as an intern, coming in to the shop each Monday to learn about floating, sanitation, and better understand the intricacies of construction projects. For every four hours I worked, I was expected to schedule myself a float as part of the curriculum. Being able to float once a week as part of my learning process would have been enough to keep me coming back week after week, but I also soon realized that I had stumbled into a very strange and special place.
I stuck around as an intern for more than 6 months before they had a part time opening. Half a year after that, I was working full time at Float On.
A source of future employees
At some point you might want to a hire an employee that you know is enthusiastic, dedicated, hard working, and you know you and your coworkers can get along with. If an intern is willing to come back week after week and work in your shop with next to no reimbursement, it is a pretty good sign that they are enthusiastic about floating.
