Teachers in Angola have gone on strike from today as they begin their three day national strike protesting over their wages and conditions of public schools, reports Reuters.

The country’s Ministry of Education has blamed the economic crisis driven by the low global crude oil prices. The current top oil producer in Africa has threatened to note all teachers that fail to attend class.

“Teachers and students who do not attend classes will be marked absent” the ministry said.

However the National Union of Teachers (SINPROF) is determined to make the government meet their claims.

“In Luanda there was about 99 percent adherence to the strike… It is true that there has been intimidation by school managers, but this is to discourage our claims,” general secretary of the National Union of Teachers (SINPROF) Fernando Lauriano told local media.
