Being afraid of getting sick is not one of the criteria for getting the PUP.
If you have a viable job to go to, you must return to it, that's the rule.
If you all returned, the job probably wouldn't be viable, but theres room for a few more.
Caiming your doing the right thing by not returning to work because you're not spreading the virus is bullshit, if that's your only reason and you believe there's work out there, then your robbing welfare.
Take basic precautions, screen/Mask/Sanitise/ventilate and the Taxi is as safe as anywhere else
