@gramajojo What kind of work will you be returning to? Will you be in close contact with a lot of people? In addition to a mask and handwashing, remember to clean frequently touched surfaces regularly with a disinfectant, alcohol or bleach. It would not be bad to ask your employer to provide this. Find out what your employer's policy will be to assure that employees stay home if they are ill or have been exposed to family members with Covid-19.
My friends who are preparing to reopen their workplace are also keeping the lunch/break room closed, asking people to bring their own food and beverages, staggering start times, limiting workers to one per vehicle, and not allowing employees to gather in groups - all meetings will remain virtual for the near future.
