The number of help-desired ads returned to pre-pandemic levels in January, particularly among industries that have weathered the pandemic quite well, an indication that hiring could pick up from its slow pace at the start of the year.Available jobs on job-search site Indeed were up 0.7% at the end of January from February 1, 2020, according to the company’s measure of job posting trends. The number of postings to the site has grown since hitting a low in May, though the pace of fresh openings has slowed in recent months.Industries that recovered hastily from the first shock of the pandemic have led growth in job openings, said Jed Kolko, chief economist at Indeed. Those industries-such as warehousing, construction and delivery services-have held steady over the course of the pandemic.
