right...but we are still asking for a law to regulate that...as distasteful as that is.
Like you, I'm not a big fan of legislation to rectify this issue. But I think it may be an appropriate law that an employee could bring up to HR. With a copy of a text message/email/phone log after hours, you could submit it to payroll and they'll have to give you overtime pay for work performed after hours.
You will see an effect of the law immediately and all the employers will start to respect their employees' time after work.
