I’m sorry to hear about your layoff. I’d suggest government, but there is a hiring freeze on for at least another couple of weeks if it’s not extended, and the possibility of a shutdown end of the month. Then on top of that, MSC is going to issue buyouts. That leaves the other services, and they don’t offer a lot of positions.
NOAA hires directly. http://www.omao.noaa.gov/find/media/video/wage-mariner-recruitment
ACOE hires through USAJOBS.gov.
Also look at the unions and headhunters. Or consider a shore job somewhere till things improve. Hope you pick something up soon. File for unemployment right away even if you don’t end up collecting.
