Maritime trade union Nautilus International is organising a protest in the Dutch port of IJmuiden with Paragon Offshore staff this coming Monday.
Borr Drilling Limited, Paragon's new owner, wants to close the former Paragon Offshore office in Beverwijk, posing a threat to more than 70 office or offshore platform jobs.
Nautilus said Paragon workers are demanding a "good social plan" after rejecting Borr’s offer for a legally-regulated transition payment.
Oslo-listed Borr, which owns 25 jack-up drilling rigs with another eight on order, could not be immediately reached for comment.
Sven Anton Maier-led Borr bought all the shares of Paragon Offshore and Paragon Enterprise Limited in late March for more than $200m. Paragon has 32 drilling units.
It has also built a large number of offshore platforms and recently placed an order worth $800 million, Nautilus said.
"A company that recently invested more than one billion US dollars cannot offer a good social plan - that could be agreed with comparable companies in the Netherlands - because it does not have sufficient resources? That is too crazy for words!"
Nautilus spokesman Bert Klein said the union has been in talks with Borr since May to avoid job losses.
"If redundancies cannot be avoided, the objective is to secure a social plan that must at least comply with what is normally agreed in the Netherlands," he said.
"This means clearly more than just the legally-regulated transition payment."
He said Nautilus is concerned that Borr is actually carrying out social dumping, where employees are replaced by lower-paid workers.
"Borr Drilling is an employer founded in 2016 and aspires to become the largest operator of mobile platforms in the world," Nautilus said.
