WTF is increase Productivity??
Here's the simplified explanation
You work 8 hours a day washing 50 toilets for $40/day
You now work 8 hours washing 100 toilets for $60/day
See? Higher productivity leads to higher pay!!
But then FT came and offer to wash 120 toilets in 8 hours for $30/day
So he get the job as he is more productive.
You can still out do him by increasing your productivity.
So it's all about you and your productivity, nothing to do with the garment.
