14,000 of 26,0000 IRS employees didn't show up for work

About 5,000 IRS workers cited hardships and did not show up for work and 9,000 others were not able to be reached, according to two congressional aides briefed on the matter.

Meanwhile, 12,000 thousand of the 26,000 in the division — which includes processing centers and call centers — who were called back from furlough showed up for work, according to one House Democratic aide.

They were called back in anticipation of the filing season beginning.

According to one House Democratic aide, the Level of Service(that's the number of calls answered) in Wage and Investment has been around 35%. The plan was 80% for filing season.

The average time to answer the phone was 25 to 40 minutes.

For context: Last filing season it was 7 to 10 minutes

The Washington Post first reported the numbers.
