hello there, so im transferring from the army to an MPGS role. As most people know this involves quite a substantial pay cut. And as i understand most people within the MPGS work other jobs. My question is well first of all how legal is this, and what are the restrictions, I would like to get an SIA licence and just do a bit of security on the side to make up the pay gap. Can anyone help me with more infomation please many thanks.
