This document provides guidance on different types of employment contracts such as zero-hours contracts, fixed-term contracts, and probation periods. For zero-hours contracts, it discusses key areas of concern like exclusivity clauses and lack of transparency. It recommends only using them where there is a genuine need and reviewing arrangements regularly. Fixed-term contracts are for limited periods and can be used for things like maternity cover. Successive use over four years deems the employee permanent. Probation periods assess suitability for a permanent role, and employers should provide feedback, consider extension or ending employment, and avoid letting periods extend over two years.
