A lot of our staple culture got taken away after the acquisition. More people in and out of our office and we felt "watched" by corporate and couldn't be our normal selves.
Sure we were the same team in the same office, but you hear that now Friday lunches may be happening less because of budget, no more unlimited PTO (I actually took less PTO when it was unlimited than now because I didn't feel pressured to use a certain number of days by the end of the year), no more team outings, no fun events. Long time pioneers got dismissed. When interacting with the corporate side of things, its a mess- you can't get a straight answer. The 401k is horrible compared to what we had before.
