This is a very important topic to ensure that your startup continues to be controlled by founders dedicated to its cause. What you want to avoid is a situation where a group of founders form a startup and each hold a similar percentage of the issued shares – without any restrictions on such shares. If only one or two of the original founders continue working for the corporation, and the rest stop, and either get other full-time jobs, move away, leave the country, etc., then the founders that are still around can be stuck and essentially handcuffed from making certain corporate decisions. If the corporation, as most due, requires the majority of the issued shares to take certain actions, and the corporation brings in other people from the outside as shareholders and/or directors (usually investors), then the founders who have stuck around will have essentially less of a say in major corporate actions. And if there is a liquidation event, then the founders who have left will get paid without having to put in the hard work.
