’Tis not the season to be hiring by Washington storekeepers, a sign Christmas may not be so jolly for workers hoping for temporary employment through the holidays, state officials said Tuesday. Although this is the time of year retailers would normally hire extra help, figures released Tuesday by the Washington Employment Security Department show a loss of 1,700 positions since September and 2,700 from last October. And unlike reductions in other service industries where job reductions have been steady since earlier in the year, most of the positions in retail have been pared in the past few months, said Chief Labor Economist Mary Ayala.
