The Westport Weston Family Y is adding about a dozen new, part-time jobs to accommodate a surge in membership since its new facility opened off Wilton Road.

The Y has scheduled job fairs on Tuesday evening, Dec. 16, and Saturday morning, Dec. 20, to interview applicants on the spot, Y spokesman Scott Smith said.

Smith said membership has soared more than 50 percent since August, and more staff is needed to serve the additional clients.

Part-time positions to be filled include lifeguards, swim instructors, child care staff, sports staff, court supervisors and facility supervisors, the Y said.

Tuesday's job fair is scheduled from 6:30 to 8:30 p.m. The Saturday fair will be from 10 a.m. to noon. Both will be at the new Y, 14 Allen Raymond Lane, off Wilton Road near the Merritt Parkway.

Smith said member visits to the new 54,000-square-foot fitness and aquatics center has been growing weekly. Since August, the Y has added 975 membership units. Units fall into categories -- youth, adult, senior or family. Many of the new membership units are family memberships, he said.
