Yes, it is important to always have an ID card, residence permit, or passport with you when going to a job. A driver's licence alone is not sufficient, as the client cannot verify your eligibility to work from it. If you do not have a (valid) ID with you, the client may send you home. We want to avoid this, as it is inconvenient for both you and the client.
If you are sent home because you do not have the correct documents, there will be consequences. You won't be able to do the job, resulting in a loss of income. Moreover, you won't be able to claim any compensation in this case. Additionally, you will receive an (extra) no-show, which will make your profile less attractive, and you risk a temporary block. Always check the travel time, dress code, and whether your ID is in your bag before you head to the job!
