Britain has basked in the sunshine this week and enjoyed scorching temperatures.
But while some have been able to sit outside and enjoy the heat, most of us have been left stuck inside an office.
The heat has made working conditions unbearable in some workplaces up and down the country.
Now, the Manchester Evening News reports trade unions are campaigning for workers to be able to go home when temperatures rise too high.
Trade Union Congress (TUC) wants office workers to be able to leave when the mercury climbs to 30C.
They say manual labour employees should go home when it hits 27C.
Employers have been advised to 'adopt cooling measures' when the workplace temperature hits 24C.
At the minute, there isn't actually a legally defined maximum or minimum temperature for the workplace.
Guidelines issued by the Health and Safety Executive, however, state the temperatures inside workplace buildings should be 'reasonable'.
TUC, which is a national trade union centre representing the majority of unions in England and Wales, say that bosses should allow workers to adopt flexible working.
This would mean staff can come in earlier or leave later to avoid hot conditions in the rush-hour commute.
The union also encourages employees to relax workplace dress codes and keep buildings cool.
TUC General Secretary Frances O'Grady said: "While many of us love to see the sun, it's no fun working in a baking office or a stifling factory.
"Bosses should do all they can to keep the temperature down.
"The easiest way for staff to keep cool inside is being able to work in more casual clothing.
"While shorts and vest tops may not be appropriate for all, nobody should be made to suffer in the heat for the sake of keeping up appearances.
"It's in bosses' interests to provide a cool and comfortable work environment.
"Workers who are unable to dress down in lighter clothing, or who work in offices without air-conditioning, fans or drinking water, are going to be tired, and lack inspiration and creativity."
