Your question is complicated, as the answer varies across the state. Basically, county directors and regional directors will work with local county governments to determine appropriate staffing levels as individual counties enter new phases of the pandemic..
As stated in the UTIA COVID-19 Guidelines and Procedures (June 3, 2020):
To help minimize exposure at work, supervisors are asked to work with all employees to identify remote working opportunities, flexible scheduling, or other creative approaches to reduce the risk of exposure while ensuring that critical responsibilities are carried out.
The UT Extension COVID-19 Re-Opening Plan refines that statement to reflect the various phases of the pandemic across the state:
County offices should be ready to adjust based on changes to CDC, state and local government and health officials’ guidance. Decisions for changes in staffing will be made in conjunction with county officials and regional directors. Data reported for each county should be considered when moving forward or backward between phases.
If you have additional questions or need clarification of your particular situation, contact your county director.
