I asked about seemingly inconsistent guidance given by a team lead (and cc'd our manager) and now I think she's upset. Don't know if I did something wrong or if I could have handled this better.

I work as a contractor and do project-based work remotely. There is a manager who assigns contractors work on projects, and also a QA team that answers questions from contractors and reviews contractors' work.

When I first started on this project, I asked a question, and the team lead gave an answer that said use Method A. So I have been using Method A since then.

About a month later, we have a team meeting where the team lead says that Method A is wrong, and we need to be using Method B. I was concerned about this, because the QA team rates our work and a low rating could prevent us from being hired for other projects at this company.

So I emailed the team lead and cc'd the manager to ask about her previous guidance and if I misunderstood it. The team lead said that there was something unique about the situation I originally asked about that justified using Method A, whereas most of the time we should be using Method B. I think this was a cop-out, IMO there's nothing unique about the first situation. But I didn't challenge it, I just accepted it and moved on.

Well now, I feel like the team lead is upset and probably is talking about me with the QA team/manager, because the QA team is giving snarky sounding answers to my questions. I feel like I'm not going to be hired back again, because the manager won't want to re-hire someone who is disliked by the team lead.

I don't know what I should do about this situation now (if there's anything). Maybe I should not have said anything at all?

Thoughts? Thank you for any advice!
