The beauty of being self employed is that you can choose your own working hours. So on a hot sunny day you can sack your customers off and fall behind because that your right to do so and the joy of being the boss.
Just don't be mardy arses when a customer ask you not to clean as it's not convenient for them that day but no, many get mardy about it as many a tbread on here would suggest.
so we have some cleaners on here who don't like to work in the sun, nor the cold and especially not on sunny days............... are they men or mice 😂
It doesn't mean you have to work like a mad man, you can take it steady and wear suitable clothing and sun protection. Drink plenty of liquids, mostly water to hydrate but also some sugars n electrolyte s to be taken into account.
However, who really cares if ones do or don't, it's each person's free will to do or not do
