I know that kind of environment too. Usually some department head is a YES person, saying the delivery can be done in some timeframe X. Then timeframe X is told to the dev team and the dev team says X + 50 days. Then the dept. head goes back to the sales team and by that time it's too late. Then the entire organization pushes down on the dev team with fury. The product is of course released in X + 75. (because you always need to double or triple the dev team estimate)

Those environments are toxic and the sign of toxicity is that the estimation process is not up for discussion (AKA the dept head keeps doing it again and again and no heads roll)
