I am a charity trustee. We are looking at possible redundancies following a sharp downturn in funding. All of our contracts of employment, signed by employees, provide for one month's notice if we (the employer) wish to terminate the contract of employment.

If we make an employee redundant, I believe that we have to terminate the contract of employment as well as dealing with the redundancy issues. With regard to the notice period, if an employee has been with us for five plus years, are we required by law to give notice of one week for each year of continuous employment? Or does the notice period of one month in the written and signed contract of employment apply?
