Most of those positions are probably for main body (October), not WINFLY (August). And a lot of them may already be filled with returning employees; positions have to be officially posted even if they already have someone in mind. That said, it’s still worth applying because ya’ never know what’s filled, what isn’t, and who’s going to bail out.
Winfly stands for Winter Fly In or some such. It is in August after the first sunrise. they pull out some WOs at that point and send down another 150-200 folks to help open the station up before Mainbody starts in Oct and the population hits 1100 or so. A lot of buildings are closed for the smaller winter crew, including work buildings and dorms. They need to be opened up and the season started in preparation for the huge and sudden influx of the Mainbody folks.
Jim, For the most part almost everyone coming in at winfly will stay on for the summer. The exceptions are some of the science groups, who come down just for the winfly season and sometimes some very limited projects with short durations.
These would be things like we purchased a service and the company is sending their own people down to do the work. Winfly is great time period for that because the station is still relatively empty and they can shut down buildings to do work. It gets much harder at mainbody after we have a thousand people here.
