Subject: Holiday compensation claim

My employment: [EMPLOYER'S NAME], [JOB TITLE]
Employment ended: [DATE]

The holiday compensation paid with my final pay does not cover all my
earned, unused holiday days / no holiday compensation has been paid at
all / the calculation appears incorrect [CHOOSE WHAT APPLIES].

By my estimate there are [NUMBER] unused, uncompensated holiday days for
the period [TIME PERIOD].

I request a written calculation of the grounds and amount of the holiday
compensation, and that the missing compensation be paid without delay. If
it is not paid, I will consider taking the matter further through my
trade union or a legal aid office.
