Please know that this post does not represent the views of all of us at this office. While I appreciate the effort to place us as a team, I feel this effort in particular does not represent the professional nature in which we conduct ourselves, and was posted without the permission of all of us on the team.
* This is not unprofessional
* It's fair if you'd prefer to opt out
* I don't believe this reflects poorly on OP at all.
Your employer is closing an office. Your team supposedly has a positive dynamic, which has value, value your employer is passing on. Why would it be unprofessional or unethical to advertise this when said employer is cutting the team loose?
I do not mean this to call out chattamatt; this comment is for those who come next who think about doing the same thing: no one is looking out for your best interests besides you. There is nothing wrong with putting an offer such as this out (except for those who may not want to participate, OP should've checked with his team for those who might have not wanted to be included)
EDIT: @chattamatt (HN commenting throttle has kicked in, I can't reply to your comment below)
I'm very sorry your team has to go through this. I hope this thread provides the necessary resources for everyone to make a successful leap to a new employment opportunity, regardless if its the entire team or individuals on their own. I can also appreciate how you feel about being represented without your consent, and my comment notes that isn't acceptable.
