Bryan Simpson, hospitality lead for Unite, said the union had been “inundated” with messages from staff worried about their livelihoods since the news emerged.
He said some workers had already had their hours cut from 32 to 24 per week, meaning they were about £400 worse off.
The company currently employs around 1,400 people and has breweries in Ellon as well as in the US, Australia and Germany.
Simpson said many of those contacting the union for advice were employed at the Ellon site.
He said: “Let’s be clear, this isn’t just the potential collapse of a brand, this is people’s jobs, this is people’s rent, how they pay their bills and their childcare and yet they are being informed about the sale of their employer through the press. That is morally unacceptable.
“We need clarity on jobs. If there are going to be redundancies, they need to be informed as soon as possible, legally and morally, because they cannot have job losses with consultation and without ensuring they get the maximum they are due.”
