Nursing staff on shift when the clocks change in the UK, the moment that marks the end of British Summer Time, are likely to work the extra hour, effectively overtime, free. Many say this October shift is challenging because it can be difficult to get the timing of observations and medication doses right. Others mention the risk nurses face who drive home from work, exhausted by the longer night shift. It seems there is no official guidance to NHS employers about additional pay for the extra hour worked.
