Answer:
Norms
Step-by-step explanation:
A norm is something that is usually done or has become a standard.
In the case of the employees, work is expected to be completed and the staff should have exited the premises by 6pm. Since this is done everyday, it is a norm.
It can be further said to be something that has become normal.
Just like in the question, submission of team outings, reports and attendance have also become a normal thing in the company, every month.
Cheers.
