Overtime, when necessary, is fully compensated according to local law, or at a rate at least equal to the regular hourly compensation rate if there is no legally prescribed premium rate. Employees are permitted reasonable days off (at least one day off in every seven-day period) and leave privileges.

We believe it is our duty to protect the environment and we do this by complying with all applicable environmental laws and regulations.
Policy on Sensitive Transactions
It is our policy to prohibit employees from entering into sensitive transactions - business dealings generally considered to be either illegal, immoral, unethical or to reflect adversely on the integrity of the company. These transactions usually come in the form of bribes, kickbacks, gifts of significant value or payoffs made to favorably influence some decision affecting a company's business or for personal gain of an individual.
Policy on Commercial Bribery
We prohibit employees from receiving, directly or indirectly, anything of value in return for using or agreeing to use his or her position for the benefit of that other person. Similarly, commercial bribes, kickbacks, gratuities and other payoffs and benefits paid to any customer are prohibited. However, this does not include expenditures of reasonable amount for meals and entertainment of customers if they are otherwise lawful and should be included on expense reports and approved under standard company procedures.

Thus, we prohibit employees from disclosing confidential or proprietary information outside the company that could be harmful to our clients, or to the company itself. Such information may only be shared with other employees on a need-to-know basis.
Policy on Conflicts of Interest
We designed our policy to eliminate conflicts between the interests of employees and the company. Since it is difficult to define what constitutes a conflict of interest, employees should be sensitive to situations which could raise questions of potential or apparent conflicts between personal interests and the company's interests. Personal use of company property or obtaining company services for personal benefit may constitute a conflict of interest.
Policy on Fraud and Similar Irregularities
