Hired out through an agency for a 6 month contract...

Hired out through an agency for a 6 month contract: 7 months later, the department had mandated 72-hour work weeks, reduced max PTO for journeyman employees and changed policy so that new employees do not start accruing PTO until one year after official hire date; at this point, I was still not officially hired, and after checking with the agency, found out that my contract had expired 2 weeks prior. Decided to put in a 1-week notice and find another job; the day I put the notice in, I was told to get out by noon and not come back.
