i have worked for this company for 16 years,this is the 1st written contract ive had,i do want to leave,i am pressured to sign a contract with these following clauses : Hours of work you normally work 40 hours each week.The company reserves the right to alter working hours as necessary.as at date of issue the company is operating on a "short time" basis.you have been made aware of this and acknowledge notification and agreement. sickness Absence the company may require you to undergo a medical examination by a medical practitioner nominated by us at any stage of your employment,and to authorise such a medical practitioner to prepare a medical report detailing the results of the examination,which you agree may be disclosed to the company.the company will bear the cost of such a medical examination.such and examination will only be requested by the company where it is reasonable to do so. changes to terms and conditions of employment the company may amend,vary or terminate the terms and conditions in this document and such change will be notified to you personally in writing or ,when generally applied ,by notice. severability The various provisions of this agreement are severable,and if any provision or identifiable part thereof is held to be invalid or unenforceable by any court of competent jurisdiction then such a invalidity or unenforceability shall not affect the validity or enforceability of the remaining provisions or identifiable parts. governing law and jurisdiction. in my eyes this is a zero hours contract which i have never agreed to,the medical clause seems draconian ,the changes to terms and conditions is this a unfair term ? and the severability clause is there because they know the contract is poor, thanks for you replies
