An email was sent on Friday and it's now Wednesday and I have no response yet. I've seen this question asked about interviews, but this was to someone in the company I already work at. I wanted to reach out the email recipient via Skype IM.
For more context if this helps:
I was supposed to have an interview for a promotion. Five minutes into the interview, the interviewer found out I'm a contractor for my company and cut the interview saying he had to speak to HR about the hoops we would need to jump through. The interviewer emailed HR on Friday, through a response to the original email setting up the interview. I would like to IM the HR rep who sent the original email setting up the interview, but I'd like to not be a bother if I haven't waited enough time.
