The poll surveyed the opinions of 2,145 professionals and workers across the country from September 10 to 17, said Asst Prof Noppadon Kannika, director of Super Poll Research Centre.
It found that 82.9 per cent agreed with the protests and their core demands, while 17.1 per cent were opposed. The poll was taken as anti-government demonstrators gathered for a mass protest in Bangkok this weekend.
More than nine out of 10 (94.1 per cent) believed the current political conflict would lead to more severe conflict and damage, as seen in previous years.
Asked to consider winners and losers in the present conflict, 71.9 per cent said the loser would be Thailand itself, via a worsening economic crisis.
Only 17 per cent supported the return of street protests, with 80 per cent opposed.
The poll showed that 92.7 per cent wanted a peaceful democracy in which political conflict was resolved in Parliament and did not spill into the street.
