February 23 is 'Work Your Proper Hours Day' organised by the TUC. It's all about getting Britain's army of office workers away from computer screens and out into fresh air. To give you somewhere cultural to eat your sandwiches, 24 Hour Museum is pleased to present ten lunchtime trails in cities around England.

Before you get out into the fresh air, just to remind your colleagues where you are off to, and why you are going, why not use this desk reminder, specially designed by the Work Your Proper Hours Team at the TUC?

Download the sign, print it out, fold it in half and plonk it on your desk one way round whilst you're away at lunch. Simply switch it round at the end of the day to show you're off on time.

The ten lunchtime city trails:

Birmingham

Brighton

Bristol

Leeds

Leicester

Liverpool

London

Manchester

Newcastle/Gateshead

Norwich

More than five million people at work in the UK regularly do unpaid overtime, giving their employers £23 billion of free work every year. If you're one, why not take some time to reflect on how well (or badly) you're balancing your life?

February 23 2007 is the day to stop and think about how hard you have been working. For more information visit the TUC's website www.worksmart.org.uk.
