You can't just disguise a mandatory training session as a “free lunch” by getting 2 boxes of day old donuts and a bottle of knock off brand coke. Especially when theres supposed to be 50 people in the room on their unpaid lunch breaks.
It also isn't a good look to call an employee “ungrateful” when he gets up to go out to his car to run home and get a real lunch after he figures out what's going on. Or to send an email later on threatening a write up for future missed sessions while calling his demand to be paid for the training as “retaliatory”
Before reciting the age old, tired utterance “Nobody wants to work anymore” : please take a long hard look at your company and place yourself in the shoes of your subordinates. Loosen up your tie and Imagine for a second that you're living paycheck to paycheck. No inheritance. No trust fund. No McMansion. And, (gasp) no nesting yachts OR private jets. You haven't had a home cooked meal in months. You're running on what essentially amounts to fumes, probably from sacrificing rest and health to work a second job (which I believe could get you fired if your boss's heart is formed from the fecal matter of a thousand cockroaches). You get the memo that the company is providing lunch today! Hooray! You might barely be over the threshold of having to choose between groceries or medication this month IF you lower your thermostat from moderately uncomfortable to bearable given you wear your coat and hat. You eagerly get to the training room and ask when the food is getting there before being directed to the stale donuts.
I'm sorry, the stale donut BOX. Containing nothing but the crumbs of poverty and defeat.
