Is working in a company as an office manager for owners who are married to the same sex permissible or forbidden?

If the company's activity is permissible, and it does not involve aiding in immorality, and working there does not result in mixing with men or being in seclusion with them; then working in it is permissible, even if the owners are non-Muslims or commit immoral acts. It is preferable that the work environment is one where immoral acts are not openly displayed.
