This is a delicate situation and your concern is a little vague, because it apparently only concerns a
suspicion. Generally, paedophiles have a morbid fear of exposure although they are often reckless, and the last thing any school wants is a scandal that could lead to heir eventual bankruptcy. You - or your friend - should be absolutely 100% sure of your facts as it would be a terrible thing to get a completely innocent person branded with such a stigma, or charged with a crime that carries severe penalties. You will need to asses what is less damaging to the school, and which is of more importance to the school owner:
- Losing a (suspected) paedophilic teacher,
or
- Losing two good, reliable teachers.
Unfortunately you do not state in which country you are employed, as not all countries have the same laws or ways of reacting to these problems. Moreover, unless your employment contracts clearly guarantee you a renewal each semester, the school will not need to "fire" you - it can quite legally simply tell you it does not need you any more, and it will not need to state a reason, however unjust this may seem.
If you are 100% sure that the problem is not just founded on pure suspicion and that the continued presence of this person clearly represents a potential danger to children, then obviously some action should be taken. In my opinion, these are your options:
- Both of you speak to the teacher and tell him what is known and the penalties he risks and that you are prepared to take action. This will not cure his problem, but it may cause him to refrain from whatever it is he is doing in the school.
- Speak to the school owner and suggest that they run some checks on the person; he may already be listed as an offender.
- Speak to the school owner and suggest that if no action is taken you will (both) go, and if you do you will cause a scandal. There are plenty of other
jobs for good teachers- Don't rely on my advice alone, ask the opinions of others too.
