I would set-up the sports fields, take out, install and collect the bases and corner flags as required, verify the activities schedule to insure that the correct teams are present and are respecting the rules, fill out daily reports, accident reports and time sheets, report any problems or incidents to their supervisor, administer first aid, and call 911 if necessary, ensure that the field conditions are safe and accessible for all users, maintain good relationships with participants and citizens.
I learned a lot of responsibility with this job as I basically was in charge of two parks. The management was very organized. I got a long very well with my supervisors. The hardest part about it was when people were not respecting the rules at the park. The most enjoyable part was working outdoors.
