You are right, as your manager the Chair cannot employ herself - there is absolutely no way she can do both roles. As for your manager signing the contract, again it is the employer who does this, not another employee.
Under the Working Time Regulations a worker who has been continuously employed by the employer for 13 weeks is entitled to a minimum of 4 weeks paid holiday per year. So if your term is at least 13 weeks long, you will be entitled to the equivalent of one weeks pay.
Any contract, whether temporary or permanent, should contain the relevant terms and conditions. Legally, this should should include:
• Employer’s and employee’s name
• Job title or brief job description
• Date employment began
• Date on which the employee’s continuous period of employment commenced
• Place of work and address of employer
• Amount of pay, how frequently paid and by what payment method
• Hours of work
• Holiday pay, sick pay, pension and maternity/paternity pay arrangements
including entitlement to public holidays
• Notice period
• Expected end date if the role is temporary or fixed term contract
• Grievance and appeal arrangements
• Disciplinary rules
• Any collective agreement
