A worker on a Zero Hours Contract sits somewhere between being employed and self-employed.
A Zero Hours Contract offers workers the flexibility they wouldn't have if they were bound by regular days and hours. They can turn work down if they’re busy, or accept work outside the standard 9-to-5 hours that many employers expect.
A worker on a Zero Hours Contract can work as many or as few hours as they like (as long as the work is available). They can also work for more than one employer. This type of contract gives workers more freedom, more variety, and the chance to boost their income with several jobs.
As an employer, if your workers are on Zero Hours Contracts you're not allowed to tie them into an exclusivity clause. And it's unlawful to discriminate against the worker because they're working for someone else.
