The UK arms of Civica, Huawei and Siemens all paid women about 40 per cent less than men in 2018-19, according to data submitted to the government.
Today is the deadline for companies in the UK to report their gender pay gap figures. More than 80 per cent of a cross-section of 100 IT suppliers, contractors, telcos and other tech businesses that are required to report, analysed by El Reg, have done so.
At the moment, Civica, which employs between 1,000 and 4,999 people, is the worst-performing business, with a median pay gap of 41.2 per cent. This is a drop from last year's data, in which it reported a median pay gap of 35 per cent.
A bigger dive was reported at Huawei Technologies (UK), which had a gap of 40.3 per cent in 2018-19, up from 28.2 per cent last year.
Siemens Industry Software had a gap of 39.9 per cent in 2018-19, while two Agilisys group companies and Hewlett-Packard's CDS also had figures of 39 per cent.
Other firms with wide gaps are: Sopra Steria at 37.4 per cent; the oh-so-ethical Salesforce EMEA, at 35 per cent; Intel Corporation (UK) at 33.9 per cent; Uber London at 32.8 per cent; and SAP at 29.2 per cent.
Familiar names that performed slightly better are Workday UK (21.7 per cent), Google UK (20 per cent), AWS UK (20.1 per cent), Vodafone (19.3 per cent) and Dell (19.2 per cent).
In what might come as a surprise for some, Oracle – which is fighting off multiple pay discrimination suits in the US, where it refuses to publish gender pay data – very nearly managed to sneak into the best-performing third, with a median pay gap of 17.2 per cent.
Also in this group are Facebook's UK tentacle (11.9 per cent), IBM UK (11.7 per cent) and Cognizant (11.2 per cent). Microsoft and Sky reported pay gaps of 7.9 and 7.8 per cent, respectively.
Moving further towards pay parity are a number of phone and comms firms. Women among the 5,000-19,999-strong staff at Carphone Warehouse earn a median of just 5.3 per cent less than men.
Meanwhile the gap was 5.6 per cent at EE and 4.3 per cent at Ericsson this year, both decent improvements on last year's gaps of 11.9 per cent and 15.9 per cent, respectively.
So far, the company closest to gender parity is HP Inc UK, where the median gap was 1.8 per cent, which represents better equality than last year, when women were paid 12.7 per cent more than men.
Two BT Group companies paid women more than men this year: PlusNet by 6.3 per cent and BT itself by 4.2 per cent, both of which are shifts in favour of women, having had pay gaps of 3.8 per cent and 2.3 per cent, respectively, last year.
Among those firms that have yet to report are Apple (UK), Kainos, Micro Focus and McAfee. They have until midnight to do so. ®
