Apply for a job only when you are 100% sure of your ability to go to work.
Because if you are chosen and you can´t show up for work, some other candidate will lose a chance to work a bit. In addition you will make a mess for company because they need to find replacement very fast.
Read the job description carefully.
Be sure that you meet all the requirements that employer has asked. E.g. that you have health certificate or valid driver’s license or some specific skill if it is needed.
After you have applied, employer will let you know if you are chosen or not.
Employer makes its choice based on information in profiles and previously obtained rating. Motivation letter is also important. As soon as employer has decided, you will get notification to your e-mail whether you have been chosen or not.
Let employer know if you cannot come to work!
If for some reason you are not able to come to work, then let employer know by cancelling your application („Cancel“ button near that specific job-offer). If you have not been accepted and asked to come to work, then the cancellation will not do any harm. Employer can then choose someone else, but please try to avoid cancelling.
You have been approved and asked to come to work, but cannot come?
First of all, let employer know as soon as possible! Please consider that if you have been asked to come to work and you will cancel, it will leave a mark to your profile and you cannot apply for any other job within 24 hours. The more applications you cancel, the longer you will be banned from opportunity to apply. And in the future employer will see how many applications you have cancelled, so it will be harder to get new opportunity. So keep your chances high by considering it carefully.
If you will not come to work and you haven´t even informed the employer?
This is the worst case that could happen. First of all, someone lost the chance to do some work and earn extra money. For employer, the work will be left undone and that causes problems and headache for everyone.
This kind of behavior will leave your profile marked with bad rating. It is quite sure that after this kind of behavior no employer will ever choose you to work.
