I've seen in some contracts clauses stating something like
If a term or condition is found to be unenforceable, the rest of the contract still remains in affect.
Is this necessary? Unless specified otherwise, if part of the contract is found unenforceable then would the entire contract be nullified?
For example if a contract states "employees must remain in the building when there is a fire" and it is found this part of unenforceable, would this be grounds for terminating the employee (anyways) because that means the entire employment contract was invalid?
