A lot of difference, but I just mention it as an example of what's in store once a few people start working for free. It becomes expected from everyone. Then it becomes the norm. Merchant bank ordinary staff didn't always work double hours for free, it began with the trading floor where the longer a trader stayed in action the more Porches he collected. Then it spread to the back office staff and finally became the norm for the whole industry.
The time to stamp on it is before it begins.
