Recently dismissed monthly-paid workers with the Unemployment Relief Programme (URP) say the recent batch of terminations has cast uncertainty over their futures.
Several workers have also raised concerns over errors in the date of termination and other inaccuracies in the dismissal letters given to them and have claimed that efforts to rectify it only lead to further bureaucracy.
On Wednesday Minister of Rural Development and Local Government Khadijah Ameen confirmed that 400 URP workers would be terminated as letters were distributed to 12 regional offices.
Ameen defended the move, as she said such changes was part of a "make work" programme aimed at tackling years of entrenched corruption.
Guardian Media understands that 700 monthly-paid workers remained on the job as of Thursday afternoon.
When Guardian Media visited one of the URP's head offices in El Socorro, several peopler were seen leaving the building with envelopes.
Some declined to speak, however one recently dismissed worker, Joan Antoine said she was given her dismissal letter on Wednesday after being called to office.
She said that due to an error in the date, she was told to visit the Ministry of Rural Development and Local Government in Kent House, Maraval, to have the situation rectified.
However a voice note circulated on WhatsApp by one disgruntled employee urged the former employees to stand their ground and insist it be rectified at their respective regional head offices.
"Please note that other colleagues went to head office this morning to get it rectified and the security did not allow them to come on the compound, however they were told to go to Kent House where the permanent secretary is to fix it.
"When you all are given your letter and it is wrong, please let them know that they have to fix it because of what has transpired."
However Antoine said she was still disheartened by the sudden notice of dismissal, noting that she has worked for the URP for ten years.
"It's ten years' of your life that just gone down the drain just so and they ain't give you nothing more than a month's pay.
"It come like you have to start over again. You ain't getting nothing from URP, they supposed to give us a package, they never give us any package... they keep bawling that they don't have any money.
"They could have just wait for the budget, do what they had to do and send we home if you so want to send us home, or they could have just demote us and bring in who alyuh want to bring in.
"Because it have plenty people out there who have nothing else to go to and they have children, so it's very sad."
Antoine said the mood in the El Socorro URP office on Thursday was "business as usual" as many have already been served their dismissal letters, noting that there were only a few employees inside.
However one visitor at the office, who asked not to be named, said she noticed a somber tone among some staff members, as the employees were particularly morose.
"They didn't seem too upbeat and it's not the usual office atmosphere, there was some uneasiness and heaviness in their movements... I could tell.
"I just came to collect something for an errand but in the short time in there it was noticeable."
Guardian Media tried to contact URP programme manager Feeroze Khan twice for comment on Thursday, but was told on both occasions that he was in a meeting and would speak at a later time.
Guardian Media understands additional letters of termination were sent to workers of the Port-of-Spain and Diego Martin offices.
