Salami slicing tactics

Salami slicing tactics are something people might do when they want to make a change to something, but they don't want to make it look like they are making a big change. For example, if someone really wanted to change their school's dress code to require uniforms, they might use salami slicing tactics to make small changes over time (like only allowing blue shirts, then only allowing solid colors, then finally requiring uniforms). This way, the change looks less noticeable because it is happening over time, rather than all at once.
