When running in the shadows, sometimes you need a way to fill your days, or to maintain your cover. This quality burdens a character with responsibilities and time commitments. While the regular income is nice, having a regular schedule and a boss to answer to doesn’t jibe well with the shadowrunning profession.
The player and gamemaster should work together to determine the job, which is usually a pretty decent gig based on the pay rates. In order to establish the legitimacy of the day job, the character must possess a valid SIN (SINner quality or at least a Rating 4 fake SIN). If they have the SINner quality, the money from the Day Job quality is considered already taxed. If they are using a fake and it gets burned or connected to a crime, expect the cops to come down hard and the job is lost until the situation is cleared up.
When combined with the Fame quality, this could easily bring in enough money to support the character, so make sure they have a good reason to run the shadows.
During a session, roll a D6 at the beginning of each day to determine if your character is supposed to be at work. On a 1, you’re scheduled for a shift and won’t be able to actively participate in the run unless you either skip work or gain one level of Fatigued. Each consecutive day without a shift adds 1 to the next D6 result that will trigger a shift (1–2 on the second day, 1–3 on day three, 1–4 on day four, etc.), which resets after each shift. For each shift you choose to skip, your next monthly lifestyle payment goes up by 100 nuyen x Lifestyle category (representing the lost income).
Each time you skip a shift, you also need to make a Charisma + Edge (1) test, and this threshold increases by one for each time you skip work. On a failed test, you’re fired from your job and may not take the Day Job quality for at least one month. On a glitch, your Heat modifier goes up by one due to nosey and suspicious co-workers. On a critical glitch, one of your co-workers has discovered that you’re a shadowrunner. They must be dealt with (a bribe of 500 nuyen x Lifestyle category will do, or you could do something more drastic), or else they’ll turn you in to the authorities—burning your lifestyle and its attached SIN.
Also, if anyone is looking for you and scores at least 4 hits on a legwork-related test - including a Matrix search - they’ll be able to connect you to your place of employment and may try to intercept you there. If they can figure out when you work.
