Dunno about you, but I ain’t making >£1000 per day, and looking round Grangemouth nor are many of that workforce. It doesn’t add up. It lacks credibility and still reeks of Jim sabre rattling for more tax rebates

I don't think you're parsing the article's information correctly which is causing you to arrive at the improper maths.

they said the plant is losing £385,000 a day.

This is the total operational shortfall, not the exact amount that is allocated to labour going to wages.

one of the oldest oil refinerys in the world, will close in spring 2025, costing almost three thousand jobs directly and in the supply chain.

The whole supply chain include not only the workers at Grangemouth operating the refinery, but lorry drivers delivering crude to the refinery and finished products out for shipping, dockers doing the same at the shipping port, all workers that process the regulatory compliance paperwork, even companies that supply repair parts/materials to the refinery, food for the canteen, etc.

So that article is saying: After all the costs and profits are tallied there is a shortfall of £385,000 at day. If it closes not only will the workers at the refinery lose their jobs, but many others will that support the refinery (but don't work in it). This could affect 3000 jobs, some of which are in the refinery, but many are not.
