Thank you. First of all, in terms of the return to your job, according to Reg. 18 of The Maternity and Parental Leave Regulations 1999, an employee who takes Additional Maternity Leave (i.e. between 6-12 months off) is entitled “to return to the job in which she was employed before her absence, or, if it is not reasonably practicable for the employer to permit her to return to that job, to another job which is both suitable and appropriate for her to do in the circumstances.”
This means that there is no guarantee of a return to the job the employee performed before going on maternity leave. If the employer can show that it is not reasonably practicable to allow a return to that job, they need to find something that is both suitable and appropriate for the employee to do instead.
When it comes to the objectives, the employer should have identified these before scoring you on them, because in effect what they have done is retrospectively added these and then told you that you are off track when you did not even what you were supposed to be working towards.
In terms of what you can do, you can raise a grievance about this to the employer and let them deal with it formally, hopefully resolving this matter amicably. If that does not work, then you really have to consider how much further you want to take it. You cannot just claim for what has happened and have to consider resigning first, which can be risky. Instead, if they eventually dismiss you as a result, which I would hope wont happen, you can consider an unfair dismissal claim. But for now, use the grievance option as that would be your best bet.
