View other staff working on the same job 

Also on the Upcoming Jobs Page, if you scroll to the far right, each of the shifts has faces icon.

Click this to bring up a list of the other staff members working with you on that particular shift and their mobile numbers. This will enable you to organise travel arrangements with these people, or you could know who to call if they are running late. (Note, your employer has to have this feature switched on at their end to make it visible.)
