The rule is that if you do any work then it counts. I include any part time other non-aviation employment in FTL schemes I have written for operators. The passengers have a right to expect that the crew are not tired and are properly rested.
In the UK CAP 371 states:
1.4 A flight crew member is required to inform anyone who employs his services as a flight crew member of all flight times and flying duty periods undertaken, whether professionally or privately, except for flying in aircraft not exceeding 1,600 kg maximum weight and not flying for the purpose of public transport or aerial work.
Aerial work includes flying instruction for which the pilot is remunerated. It is also aerial work where valuable consideration is given specifically for flying instruction, even if the pilot receives no reward.
So part time flying instruction must be declared to your employer for FTL purposes.
Currently FTL does not apply to private flights at all; except that any private flights must be recorded in CAT FTL schemes to ensure you are in limits for the CAT flight as if the private flight was a CAT flight.
However CAP 371 is not law, it is recomendation. The law is your AOC company approved FTL scheme which could vary from CAP 371.
Hope this helps
