Its important to understand that Job Boards are controlled by the Agency that hired you. Liveforce only provide the software for these agencies to manage their workforce. You need to contact the agency directly for job opportunities.
No Jobs Available
If you can see the Job Board. There may be a notice that the 'agency currently doesn’t have any jobs available'. Contact the agency that hired you for further job information.
Job Promotion
The agency that hired you can promote Jobs to certain staff when they think those staff are more suitable for certain Jobs / roles.
These Jobs / roles will not be published to your Job Board. This maybe why your friends and colleagues get Jobs offers and you don't.
Liveforce cannot help you with this and you should contact the company directly if you think you should be getting sent these promoted roles.
You'll be able to find their contact details by searching for the company name in Google or looking at any Job details in the app and contact details for the Primary Contact.
