Your employer will prepare a generic version which will be sent to you in advance of you starting in the post. Then, in your first meeting with your educational supervisor, you will discuss the schedule and personalise it further for you, according to your needs.
The final work schedule has to be agreed between both of you, so if there is anything you aren’t happy with, the guardian can step in to oversee the disagreement and find a resolution.
The contract specifies that the employer must take adequate account of reasonable requests from you when agreeing the work schedule, to ensure your work and training fits around your life.
For example, if you have caring responsibilities, you can raise this in the work schedule discussion and work with your employer to ensure the schedule is compatible with this as much as possible.
