Who would be an employer?
The real problem with this legislation is that it makes it virtually impossible to be an employer, while retaining any sense of what the relationship between employer and employee is supposed to be.
When you employ someone, you are in effect taking them on as almost a dependant; not quite a master - servant, lord - vassal or patron - client relationship, but certainly the employer has solemn obligations to the employee and vice versa. It is hard to maintain this if the employer can't decline to enter into such a relationship with someone who holds views with which he fundamentally disagrees, or who he doesn't really think is suitable for the job, as can easily happen under this legislation.
At least from the employee's point of view, we can still refuse to accept employment without any such restrictions, but for how long?
