I’m a contractor working for a consultancy who is working for a tobacco company, I was told it would be a retail client and I feel bad, not bad enough to quit immediately as i do genuinely need the money right now but I’ll leave when I can. (I tried passive aggressively quitting by insisting they put my day rate up expecting them to say no but they did)
