Zero hour contracts are contracts that do not have specified hours or shifts. They are simply the agreement to be available when needed at short notice by their employers in the event any other member of staff cannot attend or more staff are required in a busy period. An example of a zero-hour contract is also seen in Lloyds Pharmacy; individuals who are called when another is either late or cannot attend. Zero hour contracts are good for an individual to quickly work without the restrictions of routine shifts, the negative aspect of this is the fact it is not a reliable source of income for an employee as they lack consistency with their hours. There are very mixed opinions about zero hour contracts in the UK, and whilst some people find that they fit their life perfectly, others believe that zero hour contracts are immoral.Separating legally binding contracts from other agreements requires an identified offer. The must be identified via the means of advertisement – being classed as invitations to treat. Additionally, the employer making the contract offer to potential employees must have necessary authority to do so. Conditions within offers of employment must be met once documented for the contract to become valid; an example of which could be x amount of GCSE’s needed for acceptance. Any promises made by the employer towards the employee in interview conditions are legally binding. Both parties MUST gain from the contract; the employer acquiring the work of the employee and the employee guaranteeing an income. This is known as consideration.If the parties intentionally decide that the contract is not legally binding when it is drafted, it will not be able to be later enforced in court. Mistakes and misrepresentation from the parties mean that a valid contract can be brought to court. All terms of a legally binding contract must be documented in writing with signature proof; this is known as written terms.
