Jersey firms are being warned they could get a bad reputation if they do not give women the same rights as men in the workplace.
Almost three quarters of management and senior officials' jobs in the island are filled by men.
Meanwhile, women dominate the administrative and secretarial occupations in the island.
Employment lawyer Siobhan Riley, from Carey Olsen, says bosses should give women the same rights as men.
She said: "Any employer who does not take account of capable, talented young women is going to cut short a future supply of talent.
"The island is small and word of mouth is everything and employers that discriminate on grounds of sex will no doubt find that those types of decision become known in the marketplace."
