"Seventy-four percent of covered workers face a waiting period before coverage is available. Covered workers in the Northeast are less likely (64%) than workers in other regions to face a waiting period." the report reads. "The average waiting period among covered workers who face a waiting period is 2.2 months.... Thirty-one percent of covered workers face a waiting period of 3 months or more."
That percentage is even higher in West's old field -- health care -- where a full 86 percent of workers have to endure a waiting period that averages 1.9 months.
