Job boards do not allow you to include telephone numbers in job advertisements. This may be because they:
- Can't capture and track a job application
- Don't want to 'police' employers using premium rate telephone numbers (it is unlawful to charge job seekers a fee for finding work)
- Don't want you to lose an application because the call isn't answered
Additionally applicants find it a lot of hassle just to make an application when it is typically far easier to answer your common questions with a CV.
