I think the only way any one should deal with shooting out of season deer or vermin, birds on the open general licences, is to read and understand the legislation yourself.
Then ask yourself “can I put forward a robust defence for my actions if / when I am challenged in court and my licences are in question”.
Any shooter should absolutely know and understand the law. If you are being brought in to manage wildlife for others, you are being brought in for your expertise, and this is not just for your ability to shoot, but it is also for your wider knowledge on the subject.
I would also question if it brings all other shooters into disrespect.
The fact that your land owner, farmer, boss etc wants / insists that you do it is really of very little consequence when you are in the dock. Those who ask others to carry out illegal acts tend to rapidly distance themselves when you are in trouble.
