Perhaps posting a valid email and Skype address would be useful.

You can start by hiring people that are usually happy to begin with.

If most or all of your staff are not happy at work that says quite a bit about how poorly run the organization is and how bad communication is therein.

Holding meetings that accomplish nothing while talking to or at someone but not with someone achieves nothing.

The other side of the coin is that perhaps you have a bunch of wannabe foreign teachers on staff that could not make it as French chef's and they simply hate their lives and where they are at now. Maybe they are foreigners that had some fantasy about what France is-vs-what it isn't.

Another side of the coin is that perhaps they are not liking the product you are selling, which in this case is ESL.

If the program is filled with problems to include badly written text books and teachers are left to back fill the numerous errors contained therein, then sooner or later everyone knows the course is a joke and worse yet, they are part of it. In other words, the same white monkey in another venue and nothing has changed and the illusion is gone.

Maybe your DoS or principal is a loser and cannot teach him/herself and no one respects those people or that person.

Maybe your staff lacks vision and motivation.

Maybe the building exterior and interior colors are ugly and the atmosphere is bad for day-to-day working.

Maybe the French are thought to be rude by your foreign staff....
