The lack of flexibility in the IT industry coupled with longer working hours has caused around 37,000 female computer professionals to leave UK's information technology sector between 2001 and 2007.
Data compiled by the British Computer Society showed that there were nearly 230,000 women working in tech back in 2001, accounting for one in every 3 posts.
This can be partly attributed to the fact that women often have to decide between their careers and founding a family for example.
Last year, that number had fallen to around 192,000 while the overall number of IT professionals in the UK grew overall to more than one million.
Dr Jan Peters who manages the BCS Women's forum commented that "Credit crunch or not, IT industry leaders are still predicting skills shortages. And yet the number of women exiting the IT profession continues to rise alarmingly, mainly due to the lack of flexibility offered by employers."
Earlier this year, a survey carried out by IT recruitment company Interquest, found out that nine out of ten women IT professionals thought that the industry is biased against them with a staggering 33 percent experiencing sexism at work.
Another survey back in 2006 found out that half of female IT workers in UK felt underpaid when compared to their male peers.
BCS will also co-organised W-Tech 2009, an event aimed solely at women in IT in the UK, with womenintechnology.co.uk and will take place in February 2009.
