Travel contract

Call and talk to your recruiter. Contract should be binding . If you should agree to a change a new contract should be in order. My wife had contracted stating she need particular days off. When she arrived she was scheduled to work. She called her recruiter and got the issue resolved that day.

I hope this helps

Send your company an email stating that the change of contracted shift and hours is considered by you to be a breach of contract; and, upon that breach, you consider the contract null and void (since attempts to rectify the situation have been met with silence on their parts)) and therefore, consider the contract has ceased as of the first scheduled 12 hour shift at a time not contracted for.

Something like this should get attention. You also have the option to show your contract to the NM and have the NM change the shift back to what you agreed to. You are under no obligation to continue with a contract if it is breached, so you technically can leave without penalty.

Just be careful not to show up for the changed shift or it can be considered that you accepted the change in contract terms. This is not the point to renegotiate because that can also be considered implied acceptance of the new terms. Stand your ground and tell your company that you will not accept the changed terms and conditions and will be leaving their employ if the situation isn't rectified immediately. They are using silence to trap you, as this is one of the oldest sales tricks known.

Considering this is the holiday weekend.(nurses, hospitals work not THE COMPANY) The powers to be may not be available to get this resolved. I would give them till at least Tuesday...
