Unite general secretary Sharon Graham said it was the “government’s responsibility to protect jobs and industries that are a vital part of the economy”.
“Workers in the JLR supply chain must not be made to pay the price for the cyber attack,” she added.
The BBC has contacted the government for comment.
JLR’s supply chain supports 104,000 jobs in the UK and sits at the top of a pyramid of suppliers, many of whom are highly dependent on the carmaker being their main customer.
The hack, which occurred more than two weeks ago, has forced the manufacturer to shut down its computer systems and close production lines worldwide.
The crisis is thought to have cost JLR at least £50m a week. A criminal investigation is under way.
There are growing concerns that many of JLR’s suppliers, small and medium-sized firms, do not have the resources to cope with an extended interruption to business and subsequent losses.
