Another thing to take into consideration is if you have a second job, the hours from the second job are also included into the 48 Hr per week rule. The "Opt Out Agreement" is something that either employer or employee can bring to the table but, the only person who has the authority to withdraw this agreement and without notice given is the employee.
A lot of employers get the hump when you bring the working time directive up, but its there to safe guard every one, and as every one knows aviation is about peoples safety first and foremost!!
