Employment in Turkey is mainly governed by Turkish Labor Law and Trade Union Law.
Under the new Turkish Labor Law, there are four different types of job contracts:
a) Job contracts for “temporary” and “permanent” work
b) Job contracts for a “definite period” or an “indefinite period”
c) Job contracts for “part-time” work
d) Job contracts for “work-upon-call”
Job contracts do not have to be concluded in a specific format. However, if a job contract is signed for a definite period, it must be concluded in writing. Job contracts are exempt from stamp tax and other duties.
Legal 
Unless otherwise provided in the bilateral or multi-lateral agreements to which Turkey is a party, working permission for a definite period of time is given to be valid for at most one year, taking into consideration the situation in the business market, developments in the labour life, sectorial and economic conjuncture changes regarding employment, according to the duration of residence permit of the foreigner and the duration of the service contract or the work, to work in a certain workplace or enterprise and in a certain job. 
This year’s collective bargaining talks, annually slated for August, will be replaced with the collective agreement talks to be held after Parliament opens in October in line with the approved constitutional amendments granting public servants the right to a collective agreement.
