Workers employed on Jersey should have a better idea of their terms and conditions after a tightening of some parts of the island's Employment Law. An amendment which provides that days off could be averaged over a fortnight now states that employers and employees should agree such terms in writing.
Those on short-term contracts can also be protected from unfair dismissal by working at least 13 weeks.
When the law was introduced in July, it included the right to a minimum wage.
All employees were also given the right to at least two weeks' holiday pay.
