The employment contract is the basic agreement of the working world. It arises when you agree with your employer on the performance of work and the associated pay, and on other benefits and terms. The contract binds both you and your employer.
There is no set form for an employment contract. You can make the contract orally, but it is wiser to set it out in writing. An employment contract can even be made by electronic communication.
The employer must provide a written account of the terms and conditions within one month of making an oral employment contract.
