Disfellowshipping. From the Elder's Publication PAY ATTENTION
ALL THE FLOCK.
The Scriptures clearly show that Jehovah forbids certain conduct among his clean people; brothers need to uphold Jehovah's righteous standards regarding the following: ... Apostasy is a standing away from, a falling away, defection, rebellion, abandonment; it involves teaching false doctrines, supporting or promoting false religion and its holidays or interfaith activities. ... Persons who deliberately spread (stubbornly hold to and speak about) teachings contrary to Bible truth as taught by Jehovah's Witnesses are apostates. ... Working secularly for a false religious organization could put one in a position similar to that of one preaching false doctrine. ... Celebrating a false religious holiday would be similar to performing any other act of false worship. ... Idolatry. ... ( Pay Attention To Yourselves And To All The Flock, pages 93 -94 )
