You don’t want to overwhelm your staff with lots of silly rules. But that doesn’t mean you should let them ignore company rules. If you laugh off such directives, you’ll set a bad example. Example: You and your team sometimes receive e-mail warnings to stay off the Web for two hours while the computer folks install higher-speed connections. Your staff asks you whether to honor this request and you tell them to “do whatever you want.” This sets a dangerous precedent: The next time you want to impose a rule, they may not treat you seriously.
