COVID-19 is still a major health issue right now for our communities and it puts at risk required levels of staffing to ensure stable operations. We should all do our best to protect ourselves and our coworkers, using the proven tools of vaccinations, masking, social distancing, self-evaluation of symptoms, testing and quarantine if needed.

This week, the Federal Government set up a website where you can order COVID-19 test kits for self-use at home. Each household can order up to 4 test kits, shipped out within 7-12 days. You can order your test kits now so you have them when needed, by going to If you need to be tested now, the site also has resources for free testing locations in your state or you can check with your doctor or insurance carrier.

If you have questions, please speak with your supervisor to ensure you are meeting the latest protocol for employment.

Thank you for your understanding and flexibility as we work through these times of rapid change. As always, the health and safety of our employees is our top priority. You can speak with your supervisor or email for additional information.
