The leadership team is completely accessible. It may take some guts to call your CEO, President, Vice President or Director and ask for time or address an issue, but they will always make time.
Company culture starts with the employees you hire and promote - don't let managers hire homogeneously, consider the diversity and inclusion that will create a better work place overall for both entry-level and employees within. Managers need to want to stay.
The health benefits here are fantastic! On the sales side, compensation starts low, but you can make a killing in overtime and commission, once you've reached the lead level. It's worthwhile for the training. Outside of the sales department, you may not get a competitive salary, though.
In order to improve the company culture, hold management accountable. For entry-level college grads looking to have a good time and meet people, cliquey is fine and fun. Once you've been trained into a business leader, unrelated cattiness, gossip and spats are just taking away from the bottom line.
Every office is only as good as the leader in charge of it - when no one is watching. Some great managers in this company are an asset, and some only appear to be. Company leaders need to look beyond the story they're being told and take the trends of management level folks leaving as what they are.
