I just went through this a my company. The ratification and strike votes are separate, but if yo reject the contract the only leverage you have to force the company back to the table is a strike. If you do not strike, then the contract goes into effect without being ratified. This is called "backing into a contract."
no, you are wrong. A contract, if required to be ratified, it cannot "go into effect" unless it is ratified. What the next step is dependent on the requirements of existing/expiring contract, and how everybody wants to deal with things.
I can assure you that a new contract will not take effect until it is either ratified or some clause in some contract somewhere states that it takes effect without ratification.
Basically, if the contract is not ratified, the parties have several choices;
extend the existing/expiring contract
stop working until a contract is accepted (strike)
continue to work without a contract
just so you are aware, there are situations where there is no strike allowed. There are actions put into place if they cannot agree to a contract that will force some form of contract on to them but it is not up to either party as to the details.
