Mirroring the slowdown in construction volume in cold-weather months, the industry's December unemployment rate climbed to 11.4% from November's 8.6% as the industry shed 16,000 jobs. But last year also proved to be much better for the construction workforce than 2012, as the industry added an average of 10,000 jobs per month, according to the latest Dept. of Labor figures. The data reflects a split between residential work, which gained 6,200 jobs, and the non-residential and heavy-civil markets, which lost 12,900 and 8,800 jobs, respectively.
