A number of agency staff at the assembly have lost their jobs due to political crisis.
Several contracts were terminated on Friday, with more potentially under threat.
As Stormont's political parties continue to struggle to resolve their differences and restore power-sharing, it is understood that up to 13 agency workers have so far been affected by the impasse.
It is believed that two of the agency staff worked as tour guides at Parliament Buildings.
An assembly spokesman said the assembly's requirement for agency staff had "diminished".
"The assembly uses agency workers from time to time, depending on business needs. The requirement for agency workers is reviewed on an ongoing basis and is adjusted in line with business needs," he said.
"At this time the assembly's requirement for agency staff has diminished and an adjustment has been made to the numbers engaged," the spokesman said.
The assembly would not confirm the number of agency workers affected or their job roles. However a source claimed up 13 agency workers, including two tour guides, had lost their jobs.
