Orange County saw a dip in employment as most sectors cut jobs in November.

The unemployment rate also declined, an indication that the pool of individuals looking for work shrank last month.

Orange County trimmed 2,500 jobs in November. The loss came after two straight months of gains that totaled 20,000 additional jobs.

The county now counts about 1.38 million jobs.

The jobless rate fell to 8.1% from October’s 8.5% and 9.4% a year earlier, according to the state Employment Development Department.

Construction accounted for most of the job loss in November, when the sector cut 2,300 jobs from the prior month to 65,800. That’s down 1,100 from a year earlier.

About 90% of the decline in construction came from specialty trade contractors, which saw 2,000 fewer jobs.

Professional and business services posted the next largest monthly decline, cutting 1,200 jobs in November. The sector has been adding jobs for the past few months, with additions of 900 in September and 3,100 in October.
