PM Security Condition Formula

SUGGESTED

Looking for help with a formula to use as condition to allow PM to only access their own projects. Our current condition works for PM User IDs but block all others from seeing job information (accounting, assistant PMs). We have decided against file/record security at this point due to speed issues that slow system down if utilized.

Currently formula is: Operator (Sys Field) = Project Manager (JC-Job)

How can I change formula to include other users in addition to PM?
