I changed the title of the thread to Working from Home.
I've been playing a politician in the Politics career. The work from home tasks for this have so far been incredibly quick and easy: write a letter, joke about politicians, give a speech in Uptown, get to know 3 Sims in Spice Market, make an empty promise, discuss interests, stage a protest, secure vote.
Securing a vote is very easy, especially if your Sim has the Incredibly Friendly trait and good charisma (which you need to advance in the career). Use Cheerful Introduction, Brighten Day or Compliment Outfit, Promote Cause, and then Secure Vote.
