In the character editor and tools if you create an Envoy character they effects of Get’Em! seem to always be active on attacks, giving a +1 to hit and +cha on damage. While it is true this will often apply to Envoys who will want to use Get’Em! as often as they can, there are scenarios where this may not be possible. Get’Em! is an action which is either 1-action or 2-action (also modified by Size Up / Acquire Asset). if you do not use the Get’Em! action you would not get the bonuses specified. If you only use the 1-action Get’Em! you would only get the +1 attacks. If you use the 2-action your strikes get the attack and damage modifier. All these bonuses apply only to the target of Get’Em!. So attacking a non-Get’Em! foe, or striking without using Get’Em! would not apply this modifier.
What would be the best for in play is to be able to toggle Get’Em! on and off with a specified action number. 1-action, toggles the apply the +1 attack (scaling based on level). 2-action toggles the apply the +cha on damage. Then an off option to turn both off.
