I quit my staff job and took a travel assignment fully expecting to work it to completion until I found another staff job that I felt was a good fit for me. I mean, 16 weeks isn’t that long right? I applied to multiple jobs and went to interviews during this time and I did find a great staff job. However, they want me to start before my assignment is up. I plan on contacting my recruiter and giving my 2 weeks, but do I tell them the reason? Has anyone had this happen? What are the chances that they cut my travel contract themselves?
