Reading, PA.
I about to sign a contract.
Does the following terminology from the termination section of the contract mean that I have to stay the full time even in an "at will" state?
'Termination by Employee: The employee may
> terminate
> > this contract only at the end of a term, with or
> > without cause, and then only upon one hundred and
> > twenty (120) days advance written notice delivered
> > personally or by certified mail to one of the
> owners
> > of the hospital at the employer's address listed
> in
> > this agreement. If the written notice is sent by
> > certified mail, it must be restricted to be signed
> as
> > received by at least one of the owners of the
> > hospital, and it must be signed as received at
> least
> > one hundred twenty (120) days prior to the end of
