Micro-business owners in the UK's marketing industry work an average of 56 hours a week - some 75% longer than the average British working week - according to research commissioned by call handling solutions firm, Penelope.
The study found that entrepreneurs in the construction industry were working the longest week, at an average of 62 hours.
And this trend of working longer hours shows no sign of slowing down as evidenced by the recent employment statistics from the Office of National Statistics which show a 0.3% increase in hours worked during the past three months alone.
The results highlighted the commitment and investment workers in the marketing industry are making in order to make their businesses a success.
The company suggests that micro-business owners are in a virtuous cycle when it comes to time and money, as 61% of marketing business owners state that they would prefer to have more money than time.
These smaller business owners are clearly willing to invest personal time in order to reap the long-term benefit of having more money.
"These results show the hard work and dedication being invested by micro business owners in the marketing industry," said Ed Reeves, co-founder for Penelope. "Being the owner and operator of a micro business means taking on multiple roles and being everything to every customer. As such, many of these owners are both time and cash-strapped and they need to make the most of every day because the amount of time being squeeze into the working week is enormous."
