Changes to core values and interest in employee welfare and well-being. All companies go through changes during growth but so drastic that the open door policy has become non-existent. I used to be able to call a member of the HR team for anything, now I'm redirected to call "1-800-....". 'Once upon a time' when passing in the hall there was a friendly "hello, how are you?", "hows' your sister doing", "did you win the golf tournament", "Happy Birthday/Anniversary", etc. to a simple nod of the head or worse, no acknowledgement at all. Growth is very good, especially when you have been a part of it, but with growth comes challenges and changes. Unfortunately, one of the biggest challenges is how is the change is actually handled, there may not be a 'right' or 'wrong' way but there is definitely a 'good' and 'bad' way.
