Never discount the importance of money.
“Money doesn’t lead to happiness,” is what rich people say. Most people are not rich. Most people need money!
Staff must make money. Every single person has bills to pay and has ambitions for a better life. And a better life requires money.
Don’t hide behind “purpose” in order to under-pay wages.
Pay a fair wage, look after staff financially so they’re not distracted and stressed by personal financial pressures.
