Is paying a sum of money to car dealership employees in exchange for pricing spare parts, knowing that the money is paid from one's private salary, considered a bribe?

It is not permissible to work in commercial insurance companies or their offices, whereas it is permissible to work in cooperative insurance companies. There is no harm in agreeing with a car agency employee on a sum for checking the price of a spare part, provided that his employer is aware of it, because an employee is not allowed to work for anyone other than his employer during working hours without their permission.
