How Much Do SG Office Workers Make In a Day?

On the surface, looking at a monthly salary, it might seem like a lot. But assuming a person earns $4000/month net (after CPF deduction) working 5 days a week. $4000/20 days = $200/day.

Assuming a conservative figure of 9 hours work per day (usually it's more), the person earns only $200/9 = $22.22/hour.  Pretty measly amount (and less with more hours).

That's why many office people don't actually "work", disappear whenever they can & avoid getting things done. Whenever possible, pretend to be always busy. And for heaven's sake, don't answer the phone.

Organizations like the Town Councils, Housing Development Board etc...

For many jobs, the salary is less than $4000/month gross.  CPF takes at least $500 away.

A police sergeant only gets $2500/month gross to sit in the police post or settle domestic disputes. Pretty lousy salary for settling petty &/or violent domestic quarrels & neighbourly shit. The headache & mental disturbance the sergeant get from intervening in such shit = Completely not worth the time.

Assuming same conditions at 9 hrs, 5-day week. Miserable pay for an hour in your life that can't be gotten back working for some damn company that has no damn connection to you.

$3500/month net = $19.44/hour
$2500/month net = $13.89/hour
$1800/month net = $10/hour  (no better than a waitress/waiter in a pub).

$5000/month net sounds like a lot but it's only $27.78/hour.  (not even $30/hr).
$7000/month net = $38.89/hour  (still little but a little better)

Does it mean that higher paying jobs have people who are more willing to get things done? No. In fact, higher pay just makes people work even less. An empty desk.  At this higher pay, don't even need a reason or excuse why you're not there. And that's how a country or an organization falls apart.
