There is activity and there is inactivity.
Activity is defined in Shadows of Isildur; Laketown as being in game, participating and engaging with other players, emoting and reacting realistically to the world around your character. Being logged in but idling or sleeping for RL hours does not count as being active or participating.
A minimum of 3 hours of RP in a given week is required to be deemed active for non-leader roles. A minimum of 5 hours of Rp in a given week is required to be deemed active for Player's with characters in leadership roles such as Managers, Foremen, Freemen License Holders with employees, Corporals in the Merchant Guard or Citadel. Some leadership roles require more time to be considered active such as Sergeants in the Merchant Guard or Citadel are required to be active RP-wise 7 hours a week.
Inactivity is determined by playing less than the required level of hours played above per your character's role.
If your character doesn't meet the activity requirements within six weeks they will be removed from their employment if employed by an NPC such as a clan, company, the Merchant Guard, or Citadel. If your character is employed by a Freeman License Holder and you go inactive, the Player of your character's boss may submit a Support Ticket to have your employment revoked. There is no back-pay. If you go inactive, your pay during that time is forfeit.
If your character doesn't meet the activity requirements within twelve weeks players may submit a Support Ticket to 'wrap up' plots you have since abandoned, this may lead up to your character's IC death. This is aimed to prevent important positions or marriages from being bound or held up by an inactive player. It is also intended to prevent a Player from escaping IC consequences for their character's actions by going inactive and returning later as though nothing went amiss.
If your character is killed off due to inactivity and your character was jailed at the time for breaking IC laws, and you spent RPP on said character, that RPP will not be replenished. You will need to follow the RPP policies and actively play again, earning said RPP back.
