In Employment contract, day-to-day activities must be mentioned or it is optional which stated in the TN guide:
Employment contract with salary information including any bonus and equity options (although you will have to demonstrate how you have gone beyond your day-to-day activities to demonstrate that you have made a significant impact in the sector)
Evidence of employment contract with salary information including any bonus and equity options and history of earnings.
is separate from the requirement for:
2) How do I demonstrate that I have been recognised for my work outside of my immediate occupation that contributed to the advancement of the sector?
which is where it is quoted as:
You can demonstrate this by providing evidence that you have gone beyond your day-to-day profession to engage in an activity that contributes to the advancement of the sector.
I didn’t use my full contract. I got HR to write a letter just for this indicating my level, full compensation and tenure. That was a one pager.
However if I didn’t have that option, I would have created a document which contained screenshots of the important bits of the contract (salary, title, compensation) and then linked them to full document somewhere on the cloud.
