If you are doing unskilled labor, you know the kind eligible for overtime at all, you or your employees are text message and Facebook. And the Facebook part is a big maybe if they are also under 30 and not that impressionable.
Oh that have an address or two. Apple gave them one. A utility company gave them one. But its an afterthought
Huh. Good to know. Thanks =).. Ok. For the record, I am not under 30 (it's probably very obvious), and I was always a dork, even when I was under 30, way long ago in the stone age before cool cars were electric with touch screens (I'm pretty jealous of that, though).
Independent contractors I've hired all prefer text.
The gym I'm a member of uses a facebook group rather than e-mail for communcating things like changes to the regular hours or special events.
