Perth and Kinross Council has limited the number of refuse collectors to two per bin lorry, following pressure from trade union leaders.
The measure, which Unite say is already in practice across most of Scotland, was agreed following safety talks between local authority and union representatives.
Key workers emptying bins will now work in line with social distancing guidelines.
The council said it was confident the new measures will further protect staff. There hasve been no cases of coronavirus in the refuse collection sector, the local authority confirmed.
Unite’s regional industrial Officer Susan Robertson, said: “Unite fully appreciate that Perth and Kinross Council want to continue to provide their excellent waste collection service to the public.
“However, this can’t come by putting in jeopardy the health and safety of the bin operatives which was happening.
“We are pleased that following productive talks we have now been able to find an amicable solution, which puts the safety of the workers first, while providing this essential service.”
Collectors are also being provided with extra PPE, including gloves, wipes and hand washing facilities.
A Perth and Kinross Council spokesman said: “Whilst the council is confident that its working practices continue to protect its refuse crews, and there has been no confirmed cases of coronavirus within the refuse service, the council has taken the decision to take a further precautionary measure to reduce the number of employees in a cab to two, with a second loader being transported in a second support vehicle.
“The council will continue to review its working practices and will consider further changes, should national, local or industry guidance change.”
