It's a familiar scene: It's Tuesday night and you've finally settled into your couch to watch television. Your "work" Blackberry vibrates. You check it. It's an email from your boss asking for clarification on something you sent him earlier. Do you respond?

Two lawsuits were filed last month by employees and former employees of T Mobile and CB Ellis who claimed they were made to respond to messages via company-issued cell phones while off the clock. "This is about 'What is work?'" says employment attorney Dan McCoy, a question whose answer is ever-changing during this recession of unpaid furloughs and salary cuts.
