According to the BBC, the Greek government has announced that it will shut down the radio and TV services of the state broadcaster ERT.
A government spokesman said transmissions would cease early on Wednesday.
All employees, numbering at least 2,500, will be suspended until the company reopens "as soon as possible."
Unions voiced strong opposition to the move.
An engineer at the broadcaster's multimedia department who gave his name as Yannis said: "The government announced that channels will shut down at midnight - after that the screens will go black.
"According to the government, from tonight I will be unemployed. It is a complete shock. In four hours' time I will not have a job."
