(Anyone defending the employers side of this issue, I hope you are also ok with workers dropping arms and walking out the second their contractual 9-6 is over. Most reasonable employers understand the relationship is one of give and take and if they expect to their employees to do more than the bare minimum they can also expect to give ever so slightly more than technically they need to. If you're doing unpaid overtime and freaking about about calling your friend from a work phone, you are being far too deferential and fearful. In most cases employers owe you more than they explicitly give).
