Purpose ======= The "first contract date" is a usefull information for anybody who onboards new colleagues. Issue: this information is not on the "public employee" and so, visible only by hr officer (minimum). With this task, we would like make this field public and visible by any internal user in the system. In this way, we don't have to provide too many access rights to any employees. closes odoo/odoo#73552 Taskid: 2584098 Signed-off-by: Yannick Tivisse (yti) <yti@odoo.com>
