securing drill around and select

I saw a tip about securing access to only the employee's data, but I'm not getting it correct.  (Below is the code I am looking at).

I want to limit the employee to only be able to drill around / selects only on his own data.

1.  I thought that I needed to put this on the employee table,  then I tried the employee field itself - Still no luck.  The employee can select anyone and drill around on anyone.
2.  in the object - user   what is in getEmployeeID?   Is that the employee number and if so,  where does it get that data?

EMPLOYEE / PAEMPLOYEE

Employee can see themselves & those underneath them:

(

(lztrim(user.getCompany())==lztrim(table.COMPANY))&&(lztrim(user.getEmployeeId())==lztrim(table.EMPLOYEE))

||

(user.isSupervisorOfEmpInHR(lztrim(table.COMPANY),lztrim(table.EMPLOYEE)))

)

DEPBEN / EMDEPEND / HRDEPBEN

Employee can see themselves but not those underneath them (in other words, an employee's dependent information is not available to their supervisor)

(lztrim(user.getCompany())==lztrim(table.COMPANY)) && (lztrim(user.getEmployeeId())==lztrim(table.EMPLOYEE))
