Jersey's Chamber of Commerce is calling on the States of Jersey to delay the implementation of the new family-friendly laws.
If passed, the laws could give new parents a full year off to look after their children, with 6 weeks full pay.
It would extend current Family Friendly employment rights, and would include time off work to attend appointments for adoptive and surrogate parents.
The Chamber claims approving the law would pass the burden onto local businesses, forcing them to pay the benefit out of their own money.
Now, the Chamber's President, Eliot Lincoln, has written to the island's Social Security Minister to urge her to delay it until uncertainties, partly caused by Brexit, are resolved.
The proposed Family Friendly Employment Rights law is currently due to be debated on 26th March.
