Although an employment contract does not have to be in writing, if the period of employment exceeds one month and exceeds eight hours of work a week, the employer is bound to give a written statement to the employee showing his/her conditions of work, within 8 working days from the commencement of employment. A written employment contract as well as a job description are considered good practice.

Employment contracts can be definite or indefinite. The former means a fixed term contract wherein both parties usually agree on its duration, and thus incorporates an expiry date, and the latter is one wherein the employee is engaged in an employment for an indefinite period (without a limit). Excluding exceptional reasons, a fixed-term contract can be successively renewed up to a maximum period of four years after which the employee shall be considered to be under a contract of indefinite duration.
