The transportation allowance for office work can be terminated or replaced with in-kind benefits by the first party without the second party's consent. Allowances and benefits, whether financial or in-kind, are determined by the first party according to their policies and are not permanent rights, but temporary benefits that cease when no longer needed. If the second party intends to change employers, they must notify the first party in writing 120 days in advance; failing to do so will require them to pay a penalty equivalent to their last month's wage. The second party is also obligated to fulfill the contract period, and breaching this may result in a penalty of six months' wages and any additional compensation stipulated in the contract.
