A lobby, Bunge la Mwananchi, has said the decision to force the civil servants to take a pay cut is ill advised.
The group's national coordinator George Nyongesa in a statement said the cost of living is higher now than it was last year.
He asked President Uhuru Kenyatta to do away with county governments as they have caused the wage bill to skyrocket due to high salaries for county commissioners, regional commissioners and subcounty commissioners.
"Fire these idlers in the devolution system. We are sure that this move alone will return to the exchequer hundreds of millions," Nyongesa said.
"We wish to tell the President that forcing civil servants to take a pay cut is misguided and shows lack of understanding of our laws, international labour law regulations and the current socio-economic realities of Kenya's workforce," he said.
Nyongesa said the reduction of between 10 to 20 percent of civil servants' salaries will hamper access to basic needs such as food, shelter, clothing and education to most families.
Nyongesa said the move will increase the socio-economic challenges the government is grappling with such as poverty, disease burden and insecurity.
He said Kenyans voted for Jubilee because Uhuru and Deputy President William Ruto promised to bring down the cost of living and that is what they expect from the government.
Nyongesa asked the government to shelf the laptop project as it is not a priority.
