Mesa began notifying several municipal employees this week that their positions would be terminated in January because of the city's economic crisis, a spokesman said Saturday.
The number of city employees to be affected by the layoffs was not available, said spokesman Steve Wright.
The Associated Press reported that an estimated 70 employees would receive notices.
Wright said he could not confirm the number, but that no employees would need to leave before the end of the year.
"The bottom line is that with the economy the way it is there's no way we can make budget reductions (without layoffs)," he said.
Mayor Scott Smith and City Manager Chris Brady will meet with media Wednesday to explain the extent of the cuts, Wright said. He would not specify the positions that would be lost.
"The adjustments that the city has to make in this new economy are going to be comprehensive," he said of the positions that could fall under the chopping block.
A Thursday study session will allow the city to show how it is affected by the economic crisis and to plan possible solutions, he said. The city faced an unprecedented 12.5 percent sales tax revenue drop this year between June and September, losing $6.4 million compared with 2007 numbers, according to a release from deputy city manager Bryan Raines.
