What is basic workplace ethics for an organization ?

i have read an article 

-Rules and regulations ought to be same for everyone & Company’s policies need to be communicated clearly to each and every one .

- Give employees the space they require Organization should not expect employees to attend office days a year.

 -Salaries should be decided in the presence of the employee and also keeping in mind an individual’s role in the organization, his/her gross salary in the previous organization,-responsibilities within the current system and of course his/her years of experience 

-Do not be too strict with your employees
