This problem started in March when there was a big jump in people claiming they were temporarily “absent” from work for “other reasons.” The BLS noticed this and flagged it right away. In March, the BLS said the unemployment rate likely should have been 5.4 percent, instead of the official 4.4 percent rate. In April, the BLS said the real unemployment rate was likely about 19.7 percent, not 14.7 percent.
