My manager when she talks about me to another coworker in the same company
always uses my name without adding さん after it and this is only with me can I
know when we can drop using さん after a name?

question
meaning usage
Not adding san after a name
There are no simple/clear rules for when -san can be dropped, but in your case
it should be simply because you are a foreigner and your manager is following
the convention in English.

I suppose you are called by your first name alone while others (Japanese) are
called family name-san. Most probably because it is very rare that Japanese
people call each other by first names, calling **foreign** first names alone
does not sound odd just as in English (i.e., it is understood as special
cases).
