The majority of employees striking are those working at embassies around the world and their strike all but ensures that most embassy services will be cancelled Wednesday.
Four years ago, foreign ministry employees from around the globe declared a labor dispute against the state and the Ministry of Finance in an attempt to change working conditions and salaries.
According to employees, the gaps between their demands and the treasury's conditions are not large, but negotiations are still at a deadlock.
About a month ago, employees threatened a general strike due to claims of erosion in their salaries and due to delays in negotiations with the Ministry of Finance, following the implementation of a new wage model.
According to a foreign ministry employee committee, advance warning was given "to avoid embarrassment during the execution of the strike, which took a radical turn at very short notice. We are dealing with an irrational line that causes escalation in labor relations."
