Candidates recommended for appointment as assistant teachers in government primary schools began an indefinite sit-in in front of the National Museum at Shahbagh in the capital on Sunday, demanding that the government complete their appointments by August.
The demonstration began around 11am under tight police security.
A total of 14,384 candidates were recommended for appointment following the government primary school assistant teacher recruitment examination held on January 9 this year.
However, despite completing the recruitment process, the recommended candidates have yet to receive their appointment letters.
The candidates had earlier demanded that the government issue the appointment notification by July 29, but no such order was issued.
On Saturday, the Ministry of Primary and Mass Education announced that the recommended candidates would join their respective workplaces on October 29.
However, the ministry issued another notice on Sunday, bringing forward the joining date to October 1.
Protesters said they had already completed all required formalities but were still waiting for their final appointment letters, leaving them in uncertainty.
The recommended candidates had earlier staged a similar demonstration at the same venue on April 26.
At the time, State Minister for Primary and Mass Education Bobby Hajjaj assured them that the issue would be resolved.
After receiving no appointment notification by their July 29 deadline, the candidates renewed their protest on Sunday, demanding that their appointments be completed within the current month.
