Subject: Community Park Cleanup
Date: February 12
Joint Systems is a company that tries to take every opportunity to give back to our community. Therefore, I am urging all of our employees to take part in the upcoming community park cleanup sponsored by the city of Harrisburg. Without the dedication of volunteers, our parks and public spaces would not be free of litter. Donate some of your free time to keeping Harrisburg a beautiful and inviting city.
The community park cleanup will be held next Friday, February 18, from 1:00 to 5:00 P.M. Employees who wish to participate will leave work at lunchtime, yet will still be paid as if they had worked a full day. Volunteers are asked to bring supplies such as protective outerwear, tools, insect repellent, trash bags, and snacks.
A shuttle bus will depart from the company parking lot at 1:20 P.M. on Friday to take volunteers to the volunteer location. If you have a specific preference concerning the type of work you would like to do, please contact Event Organizer Don Lewis at 435- 555-6768.
We appreciate everyone’s enthusiasm and support.
