Complete New employee system guide https://patiilovepasta.blogspot.com.au/2016/11/new-employee-expert-system-guide.html

all rite Pati hid this very well. took us 5 days to find where to purchase 4 new employee.  

so here we go.
-go to new dressing room
-next to ur character name tap on arow down
-tap on button on bottom left
-purchase the employee, insert name etc
-repeat 4 times if u want to buy all 4

note:
-they will be in dressing room coz max u can have to go ingredient shopping is 7.
-u can swap them by pulling some of ur staff to dressinh room and bring them there.
-u can dress them up etc.
