Time is something that everyone cares about despite their ethnicity or religion.
Having worked for more than half a decade in the hospitality, I have experienced how much people do not value your time.
They send you home when the restaurant isn’t busy, and they expect you to stay longer when the premises is full. You are paid hourly and your contract is usually casual.
This is wrong itself, but it gets worse. You make plans based on your weekly shifts and you end up being in a limbo in which the time you allocate to sort your life outside your workplace gets constantly messed up.
I believe that if you want your employees to be performing at their very best, you need to respect and value their time. Period.
