During the consultantion period, my employers provided a formal letter as part of the process stating payments I would be entitled to if made redundant. This included payment for holiday outstanding and quoted a specific payment figure (I have not used any holiday so far this year). I have now received my formal redundancy letter which states that I must take the outstanding holiday as part of my notice period, so no payment for untaken holidays. When I queried this, I was given the reason that the original letter was 'a mistake'. My contract of employment incidentally states that during a notice period, being paid for untaken holiday or having to take it as part of the notice period is at the discretion of the management.
