One worker, contractor Michael Simpson, said everyone was delighted with the news. He said: "A lot of contractors can struggle at this time of year so to get jobs back is a big sigh of relief for everyone and the community as well, the small businesses will be able to keep open.
"People have been down over the last few days because of what's been happening, which is obvious, but now things are hopefully going to get back to normal.
"It looks like the plants are starting to go back on line and that's a good start.
"This doesn't just affect Grangemouth, it affects everywhere outwith the town, contractors come from all over, haulage drivers, scaffolders, so keeping the work going is just a relief."
At the Avongrange Hotel on Kersiebank Avenue, patrons were crowded into its public bar, The Grange for their Friday afternoon pints.
And virtually all they were discussing was the dramatic reprieve for the plant. On Wednesday, manager Kirsty Muir had lamented that 11 contractors who had been staying at the hotel while working for Ineos had already left.
Yesterday, Suzanne Taylor, a hotel worker, reported a more upbeat atmosphere.
"People are much happier today," she said. "It's the main topic of conversation at the moment.
"I was convinced the plant was gone for good. I was shocked when I heard the latest news on the radio this morning. It's amazing news for everybody.
"I think the whole town is happy at the moment.
"It's great news, especially for the workers and their families - but for us as well," she added. "I'm not going to lie - we're very happy."
