A few years ago, LP and the local police interviewed (and interrogated) several employees about drug dealings occurring within our center. Although none of us physically punched out, the time spent being interviewed was pulled from our time card.
Most UPS managers are completely unaware of employment law.
That time got coded out so some other department got charged with the time. IF they didn't get paid for that time then they should have filed a grievance as it was job related.
If more union employees new and followed the contract and made there management team do the same they wouldn't be getting screw out of time / money.
